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: 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 a Norwegian pastor, John Qualen was born in British Columbia. After his family moved to Illinois, Qualen won a high school forensic contest, which led to a scholarship at Northwestern University. A veteran of the tent-show and vaudeville circuits by the late '20s, Qualen won the important role of the Swedish janitor in the Broadway play Street Scene by marching into the producer's office and demonstrating his letter-perfect Scandinavian accent. His first film assignment was the 1931 movie version of Street Scene. Slight of stature, and possessed of woebegone, near-tragic facial features, Qualen was most often cast in "victim" roles, notably the union-activist miner who is beaten to death by hired hooligans in Black Fury (1935) and the pathetic, half-mad Muley in The Grapes of Wrath (1940). Qualen was able to harness his trodden-upon demeanor for comedy as well, as witness his performance as the bewildered father of the Dionne quintuplets in The Country Doctor (1936). He was also effectively cast as small men with large reserves of courage, vide his portrayal of Norwegian underground operative Berger in Casablanca (1942). From Grapes of Wrath onward, Qualen was a member in good standing of the John Ford "stock company," appearing in such Ford-directed classics as The Long Voyage Home (1940), The Searchers (1955), Two Rode Together (1961), and The Man Who Shot Liberty Valance (1962). John Qualen was acting into the 1970s, often appearing in TV dramatic series as pugnacious senior citizens.

Trivia: American actor Claude Johnson has played supporting roles on stage, screen and especially television during the '60s and '70s.

Trivia: Though best known to modern filmgoers as a horror star, cadaverous John Carradine was, in his prime, one of the most versatile character actors on the silver screen. The son of a journalist father and physician mother, Carradine was given an expensive education in Philadelphia and New York. Upon graduating from the Graphic Arts School, he intended to make his living as a painter and sculptor, but in 1923 he was sidetracked into acting. Working for a series of low-paying stock companies throughout the 1920s, he made ends meet as a quick-sketch portrait painter and scenic designer. He came to Hollywood in 1930, where his extensive talents and eccentric behavior almost immediately brought him to the attention of casting directors. He played a dizzying variety of distinctive bit parts -- a huntsman in Bride of Frankenstein (1935), a crowd agitator in Les Miserables (1935) -- before he was signed to a 20th Century Fox contract in 1936. His first major role was the sadistic prison guard in John Ford's Prisoner of Shark Island (1936), which launched a long and fruitful association with Ford, culminating in such memorable screen characterizations as the gentleman gambler in Stagecoach (1939) and Preacher Casy ("I lost the callin'!") in The Grapes of Wrath (1940). Usually typecast as a villain, Carradine occasionally surprised his followers with non-villainous roles like the philosophical cab driver in Alexander's Ragtime Band (1938) and Abraham Lincoln in Of Human Hearts (1938). Throughout his Hollywood years, Carradine's first love remained the theater; to fund his various stage projects (which included his own Shakespearean troupe), he had no qualms about accepting film work in the lowest of low-budget productions. Ironically, it was in one of these Poverty Row cheapies, PRC's Bluebeard (1944), that the actor delivered what many consider his finest performance. Though he occasionally appeared in an A-picture in the 1950s and 1960s (The Ten Commandments, Cheyenne Autumn), Carradine was pretty much consigned to cheapies during those decades, including such horror epics as The Black Sleep (1956), The Unearthly (1957), and the notorious Billy the Kid Meets Dracula (1966). He also appeared in innumerable television programs, among them Twilight Zone, The Munsters, Thriller, and The Red Skelton Show, and from 1962 to 1964 enjoyed a long Broadway run as courtesan-procurer Lycus in A Funny Thing Happened on the Way to the Forum. Though painfully crippled by arthritis in his last years, Carradine never stopped working, showing up in films ranging from Everything You Always Wanted to Know About Sex But Were Afraid to Ask (1972) to Peggy Sue Got Married (1984). Married four times, John Carradine was the father of actors David, Keith, Robert, and Bruce Carradine.

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: American actor Selmer Jackson first stepped before the cameras in the 1921 silent film Supreme Passion. Silver-haired and silver-tongued, Jackson so closely resembled such dignified character players as Samuel S. Hinds and Henry O'Neill that at times it was hard to tell which actor was which -- especially when (as often happened at Warner Bros. in the 1930s) all three showed up in the same picture. During World War II, Jackson spent most of his time in uniform as naval and military officers, usually spouting declarations like "Well, men...this is it!" Selmer Jackson's final film appearance was still another uniformed role in 1960's The Gallant Hours.
