Trivia: Big, burly Dan Blocker only did a handful of movies in his 17-year acting career, but he became one of the most beloved and popular television stars of the 1960s for his portrayal of Hoss Cartwright on the Western series Bonanza. Weighing 14 pounds at birth, Blocker was the largest baby ever born in Bowie County, TX. At 18, he stood 6'3" and weighed close to 300 pounds, and was legendary for his physical prowess. Blocker attended the Texas Military Institute and studied for his B.A. at Sul Ross State College, where he initially majored in athletics. His build accidentally led him to the drama department for a production of Arsenic and Old Lace -- a stage hand was needed who was big and strong enough to quickly remove the dummies representing corpses on the set, between acts. While working on the production, Blocker was bitten by the acting bug and switched his major to drama. He pursued his theatrical aspirations in earnest after graduation, working in one season of summer stock before he was drafted. Blocker served in combat during the Korean War, after which he earned a master's degree, married, moved to Los Angeles, and settled down to raise a family, earning his living as a high school teacher. It was his successful audition for the small role of a cavalry lieutenant on Gunsmoke during the 1956 season, in the episode "Alarm at Pleasant Valley," that rekindled Blocker's interest in an acting career. Over the next three years, he took any work that he could get, on programs like Sgt. Preston of the Yukon, Cheyenne, Tales of Wells Fargo, Zane Grey Theater, Wagon Train, Colt .45, Zorro, Maverick, and Richard Diamond, Private Detective. Blocker also got some movie work, portraying a bartender in the offbeat murder mystery The Girl in Black Stockings and an android in Outer Space Jitters, a very late Three Stooges short. His career took an upturn when he got a guest-starring role in an episode of the series The Restless Gun, starring John Payne, in 1958; his work was good enough to catch the attention of the producer, David Dortort. A year later, Dortort was putting together a new, hour-long Western series called Bonanza and cast Blocker in the role of "Hoss" Cartwright, the big-boned, good-natured middle son in a ranching family near Virginia City, NV, set in the mid- to late 19th century (the time frame of Bonanza was always vague, with stories shifting between the early 1860s to the 1870s and 1880s). Blocker's character's real name, incidentally, was Eric, but Hoss -- a nickname from his mother's Norwegian language that meant "friend" -- was what he was known as to everyone on the series and all viewers. Despite the weaknesses in the scripts during the early seasons, the role was a dream part for the actor, who got a chance to display his gentle, sensitive side as well as his gift for comedy, and also work in a serious dramatic context as well on many occasions, and show off his brute strength as well. It is arguable that Blocker was the most popular member of the cast during the 1960s; he was especially beloved of younger viewers, in part because his character was always very sympathetic to children. In contrast to the other stars of the series, Blocker's big-screen career wasn't halted by his work on Bonanza. He appeared in The Errand Boy, playing himself in an uncredited cameo, and played a role in the Frank Sinatra movie Come Blow Your Horn. Blocker got his first major movie part five years later in the Sinatra film Lady in Cement (1968), playing Waldo Gronsky, a burly, potentially murderous thug who hires private detective Tony Rome (played by Sinatra) to find his missing girlfriend. By the end of the 1960s, Blocker was taken seriously enough as an actor to star in two features, Something for a Lonely Man, a beautiful and poignant Western/comedy-drama, and the broader comedy The Cockeyed Cowboys of Calico County. Some of Blocker's television appearances separate from Bonanza also reflected his personal side -- his politics were essentially liberal Democratic (in sharp contrast to the conservative Republican sympathies of his co-stars Michael Landon and Lorne Greene), and he appeared in several public service announcements promoting brotherhood and racial tolerance, as well as on one television special that gently satirized American popular culture, starring Henry Fonda. He was also part of the liberal contingent in the 1971 John Wayne-hosted patriotic special Swing Out, Sweet Land. In 1972, Blocker was chosen for what could have been the breakthrough role to a major movie career, when he won the part of Roger Wade, the has-been author in Robert Altman's revisionist detective movie The Long Goodbye. In May of that year, however, he went into the hospital for routine gall bladder surgery, and during recovery he died suddenly of a blood clot in his lung. Sterling Hayden replaced Blocker in The Long Goodbye, which was dedicated to the actor's memory. Blocker's passing, immediately before the shooting for the 1972-1973 season of Bonanza was to begin, signed the death knell for the series. The cast and crew were genuinely shaken by his sudden death; scripts had to be hastily rewritten to explain the passing of Hoss Cartwright, and Blocker's absence and the reason behind it removed any element of lightheartedness that the series had displayed. The final season, despite the best efforts of surviving stars Lorne Greene, Michael Landon, and David Canary, was characterized by grim, downbeat stories and a dark mood that seemed to repel longtime viewers. Coupled with this change in tone, the NBC network moved Bonanza from its longtime Sunday nighttime slot to Tuesday nights, where it died a quick death, cancellation coming halfway through the 1972-1973 season. Blocker left behind a wife and four children, among them actor Dirk Blocker and director/producer David Blocker. He also left behind a legacy of good will that survives to this day, as Bonanza is in perpetual reruns on various cable channels, decades after its cancellation. Significantly, the final season, in which he did not appear, is the body of episodes that is shown (and requested) the least of its 14 years' worth of programs.

Trivia: Pernell Roberts worked such odd jobs as butcher, forest ranger and tombstone-maker while studying acting and singing and scouting around for off-Broadway jobs. Roberts' film debut, in a characteristic Deep Brooder role, was in 1958's Desire Under the Elms. From 1959 through 1966, Roberts co-starred as black-clad, taciturn Adam Cartwright on Bonanza. "Aloof, rebellious and outspoken" was how Bonanza producer David Dotort summed up Roberts, who fought tooth and nail over every real or imagined challenge to his integrity (his biggest beef was that he had to call Lorne Greene "Pa" rather than "Father"). Fed up with what he perceived as the series' declining quality, Roberts left Bonanza in 1966; it was explained to fans that "Adam" had left to study at a European university. Free of his TV series commitment, Roberts returned to his first love, the stage--and also divested himself of the toupee he'd been forced to wear as Adam. The actor played the straw-hat circuit in such musicals as Camelot and The King and I, all the while accepting film and TV roles that came up to his standards. Unfortunately, his stubbornness and standoffishness left a sour taste with co-workers and fans alike, and Roberts was unable to soar to the artistic heights to which he aspired. After years of declaring that he'd never again return to the grind of weekly television, Roberts accepted the role of Dr. "Trapper" John McIntyre, chief of surgery at San Francisco memorial hospital, in the seven-season (1979-86) M*A*S*H spin-off Trapper John MD. In 1991 Pernell Roberts assumed the hosting duties of the TV anthology FBI: The Untold Stories.

Trivia: The son of a Jewish movie-publicist father and an Irish Catholic musical-comedy actress, Michael Landon grew up in a predominantly Protestant New Jersey neighborhood. The social pressures brought to bear on young Michael, both at home and in the schoolyard, led to an acute bedwetting problem, which he would later dramatize (very discreetly) in the 1976 TV movie The Loneliest Runner. Determined to better his lot in life, Landon excelled in high school athletics; his prowess at javelin throwing won him a scholarship at the University of Southern California, but a torn ligament during his freshman year ended his college career. Taking a series of manual labor jobs, Landon had no real direction in life until he agreed to help a friend audition for the Warners Bros. acting school. The friend didn't get the job, but Landon did, launching a career that would eventually span nearly four decades. Michael's first film lead was in the now-legendary I Was a Teenage Werewolf (1957), widely derided at the time but later reassessed as one of the better examples of the late-'50s "drive-in horror" genre. The actor received his first good reviews for his performance as an albino in God's Little Acre. This led to his attaining the title role in 1959's The Legend of Tom Dooley, which in turn was instrumental in his being cast as Little Joe Cartwright on the popular TV western Bonanza. During his fourteen-year Bonanza stint, Landon was given the opportunity to write and direct a few episodes. He carried over these newfound skills into his next TV project, Little House on the Prairie, which ran from 1974 to 1982 (just before Little House, Landon made his TV-movie directorial bow with It's Good to Be Alive, the biopic of baseball great Roy Campanella). Landon also oversaw two spinoff series, Little House: The New Beginning (1982-83) and Father Murphy (1984). Landon kept up his career momentum with a third long-running TV series, Highway to Heaven (1984-89) wherein the actor/producer/director/writer played guardian angel Jonathan Smith. One of the most popular TV personalities of the '70s and '80s, Landon was not universally beloved by his Hollywood contemporaries, what with his dictatorial on-set behavior and his tendency to shed his wives whenever they matured past childbearing age. Still, for every detractor, there was a friend, family member or coworker who felt that Landon was the salt of the earth. In early 1991, Landon began work on his fourth TV series, Us, when he began experiencing stomach pains. In April of that same year, the actor was informed that he had inoperable pancreatic cancer. The courage and dignity with which Michael Landon lived his final months on earth resulted in a public outpouring of love, affection and support, the like of which was seldom witnessed in the cynical, self-involved '90s. Michael Landon died in his Malibu home on July 1, 1991, with his third wife Cindy at his side.

Trivia: Born in the Bronx, NY, to an upper-middle-class Irish family, Carroll O'Connor's father was a well-connected attorney and his mother was a school teacher. The family lived well, in the Forest Hills section of Queens, until O'Connor's father ran afoul of the law and was convicted of fraud. Despite this setback in the family's well-being, O'Connor managed to attend college and considered a career as a sportswriter, but those aspirations were interrupted by the outbreak of World War II. Rejected by the United States Navy, he enrolled instead in the Merchant Marine Academy, but he later abandoned that pursuit, instead becoming a merchant seaman. After the war, O'Connor considered journalism as a career, but a trip to Dublin in 1950 changed the course of his life, as he discovered the acting profession. While attending college in Dublin, he began appearing in productions of the Gate Theater and also at the Edinburgh Festival, where he played Shakespearean roles. Returning to New York in 1954, he and his wife worked as substitute schoolteachers while he looked for acting work, which he found, after a long dry spell in which he despaired of ever getting a break, in Burgess Meredith's production of James Joyce's Ulysses. O'Connor got a role in which he received favorable notice from the critics, and that, in turn, led to his breakthrough part, as a bullying, greedy studio boss in an off-Broadway production of The Big Knife. O'Connor jumped next to television, at the very tail-end of the era of live TV drama in New York. Beginning in 1960 with his portrayal of the prosecutor in the Armstrong Circle Theater production of The Sacco-Vanzetti Story, he established himself on the small screen as a good, reliable character actor, who was able to melt into any role with which he was presented. Over the next decade, O'Connor worked in everything from Westerns to science fiction. He played taciturn landowners, likable aliens, enemy agents (on The Man From U.N.C.L.E., in "The Green Opal Affair"), and other character roles with equal aplomb. He also appeared in several unsold television pilots during the 1960s, including The Insider with David Janssen, and Luxury Liner starring Rory Calhoun, playing character roles; and he did a pilot of his own, Walk in the Night -- directed and co-written by Robert Altman -- in which he co-starred with Andrew Duggan. O'Connor's movie career followed quickly from his television debut, starting with appearances in three dramatic films (most notably Lonely Are the Brave) in 1961. He was one of many actors who managed to get "lost" in the sprawling 20th Century Fox production of Cleopatra, but he fared better two years later in Otto Preminger's epic-length World War II drama In Harm's Way. O'Connor, playing Commander Burke, was very visible in his handful of scenes with John Wayne and Kirk Douglas, and Preminger thought enough of the actor to mention him by name along with the other stars in the film's trailer. He had major supporting roles, serious and comedic, respectively, in such high-profile movies as Hawaii and What Did You Do in the War, Daddy?, of which the latter proved critical to his subsequent career. O'Connor had been in demand for television roles since the early '60s. In an episode of The Outer Limits, he revealed his flexibility by playing a somewhat befuddled alien investigator from Mars, masquerading as a pawnshop owner in a seedy section of New York, and jumping from a slightly affected, carefully pronounced diction in one line to a working-class dialect and manner in the same shot (for benefit of a human onlooker in the scene). He had also given a very warm, memorable, and touching performance in "Long Live the King," an episode of Voyage to the Bottom of the Sea, and producer Irwin Allen had wanted O'Connor for the role of Dr. Smith on Lost in Space early in the character's conception, when the Smith figure was thoroughly villainous. Although he didn't get the part of Dr. Smith, O'Connor later appeared in "The Lost Patrol" episode of Allen's science fiction series The Time Tunnel. He had also been up for the role of the Skipper in Sherwood Schwartz's series Gilligan's Island, a role that was finally won by Alan Hale Jr. At the end of the 1960s, while O'Connor was busying himself in movies ranging from Westerns to crime films and mysteries, including Warning Shot, Waterhole No. 3, Marlowe, and For Love of Ivy, and distinguishing himself in all of them, CBS began preparing a television series called Those Were the Days. Adapted from a British series, it dealt life from the point-of-view of Archie Bunker, a fed-up, bigoted working-class resident of New York's outer borough of Queens. The network had tried for a big name, approaching Mickey Rooney to play the part, but he turned it down, and then co-producer Bud Yorkin remembered O'Connor's blustery comic performance as General Bolt in What Did You Do in the War, Daddy? O'Connor was offered the role and accepted. He was as busy as ever with movie work, including his portrayal of a memorably boisterous and comical general in Kelly's Heroes, which was shot in Europe in 1970, and the series -- now called All in the Family -- didn't seem a likely or essential prospect for success. Within weeks of All in the Family's premiere in January of 1971, however, O'Connor had become one of the most recognizable and popular leading men on television. O'Connor had never played more than major supporting roles in movies, so there were no feature films to license starring the new pop culture hero; but CBS did pull Walk in the Night, the unsold pilot from three years earlier, starring O'Connor as a detective in a race against time to save a man's life, and aired it with the kind of fanfare normally reserved for major feature films. From 1971 on, O'Connor never looked back: He got star billing the next year in the network television production Of Thee I Sing (1972), and got his first chance to star in a feature film in Law and Disorder, in 1974. O'Connor would play nothing but leads from then on, and command a leading man's salary, a matter that led to a contractual dispute in 1974 that resulted in the actor absenting himself from All in the Family for a series of shows before it was resolved. From then on, entire productions, such as the TV-movie adaptation of The Last Hurrah (1977), would be built around him. He also returned to the theater periodically with far less success, starring in and directing a handful of theatrical productions that seldom got good notices or lingered long on-stage. O'Connor earned four Emmy awards as Archie Bunker, a recognition of the convincing mixture of warmth and anger that he brought to the character, and such was his popularity in the role, that he was able to parlay it into a spin-off series for four seasons called Archie Bunker's Place. It seemed for a time in the 1980s that O'Connor would be forever locked into the role, until 1987 when he got the part of laconic small-town Southern police chief Bill Gillespie in the television series In the Heat of the Night. Taking over a part originated on screen by Rod Steiger, O'Connor rebuilt the character from the ground up, making Gillespie a strong-willed, yet soft-spoken, flawed, sometimes crude, even occasionally bigoted man who was learning to be better. His work in the series earned O'Connor an additional Emmy, and he eventually took over control of the production, transforming In the Heat of the Night from a routine cop show into one of the better dramatic series of its era, with police work only incidental to its content (and hardly a car chase in sight), in a run lasting through 1994.

Trivia: White-haired, patriarchal Canadian actor Lorne Greene attended Queen's University in pursuit of a chemical engineering degree. Amateur college theatricals whetted his appetite for the stage, and upon graduation he decided upon a performing career. He started out on radio, eventually emerging as Canada's top newscaster, designated "the voice of the CBC" (For a while, Greene managed a mail-order announcer's school; one of the "pupils" was Leslie Nielsen). Moving to New York in 1950, Greene became a stage, film and TV actor, co-starring on Broadway with Katherine Cornell in Prescott Proposals and in films with the likes of Paul Newman, Ginger Rogers and Joan Crawford, generally in villainous roles. In 1959, Greene was cast as Ben Cartwright, owner of the Ponderosa ranch and father of three headstrong sons, in TV's Bonanza. He would hold down this job until 1972; during the series' run, Greene unexpectedly became a top-ten recording artist with his hit single "Ringo." Upon the cancellation of Bonanza, Greene vowed he'd retire, but within one year he was playing a private detective on the brief TV weekly Griff. Five years later, he starred on the network sci-fier Battlestar Gallactica. Active as chairman of the National Wildlife Foundation, Greene put forth the organization's doctrine in his popular syndicated TV series Lorne Greene's Last of the Wild. His final weekly television appearance was on the 1980 adventure series Code Red. In 1987, Lorne Greene was all set to recreate Ben Cartwright for the 2-hour TV movie Bonanza: The Next Generation, but he died before shooting started and was replaced by John Ireland.

Trivia: A Broadway actor since 1931, Philip Ober first appeared before the cameras in 1951, when he was invited by actor/director Mel Ferrer to play a supporting role in The Secret Fury (1951). Adept at portraying executive types who seemed to be up to something shady, Ober was often as not cast as a corporate villain. His most famous film role was in the 1953 Oscar-winner From Here to Eternity as the hateful Army officer who, while his wife, Deborah Kerr, carries on an affair with Burt Lancaster, tries to strongarm Montgomery Clift into entering a boxing competition. Ober voluntarily gave up his acting career in the mid-'60s when he joined the U.S. Consular Service in Mexico. Married three times, Philip Ober was the former husband of I Love Lucy co-star Vivian Vance.

Trivia: Had he been born a decade earlier, American actor Denver Pyle might well have joined the ranks of western-movie comedy sidekicks. Instead, Pyle, a Colorado farm boy, opted for studying law, working his way through school by playing drums in a dance band. Suddenly one day, Pyle became disenchanted with law and returned to his family farm, with nary an idea what he wanted to do with his life. Working in the oil fields of Oklahoma, he moved on to the shrimp boats of Galveston, Texas. A short stint as a page at NBC radio studios in 1940 didn't immediately lead to a showbiz career, as it has for so many others; instead, Pyle was inspired to perform by a mute oilfield coworker who was able to convey his thought with body language. Studying under such masters as Michael Chekhov and Maria Ouspenskaya, Pyle was able to achieve small movie and TV roles. He worked frequently on the western series of Roy Rogers and Gene Autry; not yet bearded and grizzled, Pyle was often seen as deputies, farmers and cattle rustlers. When his hair turned prematurely grey in his early '30s, Pyle graduated to banker, sheriff and judge roles in theatrical westerns -- though never of the comic variety. He also was a regular on two TV series, Code 3 (1956) and Tammy (1966). But his real breakthrough role didn't happen until 1967, when Pyle was cast as the taciturn sheriff in Bonnie and Clyde who is kidnapped and humilated by the robbers -- and then shows up at the end of the film to supervise the bloody machine-gun deaths of B&C. This virtually nonspeaking role won worldwide fame for Pyle, as well as verbal and physical assalts from the LA hippie community who regarded Bonnie and Clyde as folk heroes! From this point forward, Denver Pyle's billing, roles and salary were vastly improved -- and his screen image was softened and humanized by a full, bushy beard. Returning to TV, Pyle played the star's father on The Doris Day Show (1968-73); was Mad Jack, the costar/narrator of Life and Times of Grizzly Adams (1978-80); and best of all, spent six years (1979-85) as Uncle Jesse Duke on The Dukes of Hazzard. Looking stockier but otherwise unchanged, Denver Pyle was briefly seen in the 1994 hit Maverick, playing an elegantly dishonest cardshark who jauntily doffs his hat as he's dumped off of a riverboat. Pyle died of lung cancer at Burbank's Providence St. Joseph Medical Center at age 77.

Trivia: The son of veteran vaudeville headliner Julius Tannen and the brother of actor Charles Tannen, William Tannen entered films as a Columbia contractee in 1934. Along with several other young stage-trained performers, Tannen was "discovered" by MGM in 1938's Dramatic School. During his subsequent years at MGM, he was briefly associated with three top comedy teams: He played Virginia Grey's brother in the Marx Brothers' The Big Store (1941), a Nazi flunkey in Laurel and Hardy's Air Raid Wardens (1943), and a "hard-boiled" assistant director in Abbott and Costello in Hollywood (1945). On TV, William Tannen was seen in the recurring role of Deputy Hal on the weekly Western Wyatt Earp (1955-1961).

Trivia: In films from 1939, character actor Dan White trafficked in small-town blowhards and rustic constables. Often unbilled in bit roles, White was occasionally afforded such larger roles as Deputy Elmer in Voodoo Man (1944), Millwheel in The Yearling (1946) and Abel Hatfield in Roseanna McCoy (1949). He remained active until the early 1960s. The "Dan White" who appeared in 1977's Alien Factor is a different person.

Trivia: Craggy character actor Roy Engel made his first film appearance in the 1949 noir classic D.O.A. He quickly established himself as a regular in such science fiction films as The Flying Saucer (1950), Man From Planet X (1951), and The Colossus of New York (1958). When not dealing with extraterrestrials, he could be seen playing sheriffs, bartenders, and the like in such Westerns as Three Violent People (1955) and Tribute to a Bad Man (1956). Among Roy Engel's last films was Kingdom of the Spiders (1977) which combined elements of both sci-fi and Westerns.
