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: Television and movie actor John Larkin -- not to be confused with the identically named African-American actor who worked in movies during the 1930s, or with the similarly named screenwriter/producer-director of the 1930s, 1940s, and 1950s -- was an extremely busy radio actor at the start of his career. Born in Oakland, CA, in 1912, he rose to stardom in 1947 when he became the fourth (and last and longest-serving) actor to portray the role of Perry Mason in the radio series of that name. He played the part until the end of the series' run in 1955. At that point, he was cast in the role of District Attorney Mike Karr in The Edge of Night, a daytime television drama that was originally conceived as a Perry Mason spin-off. During this same period, he had already been very active on television; Larkin's strong delivery and vocal demeanor made him a natural as a narrator, and it was in that capacity that he came to the small screen at the start of the 1950s on Farewell to Yesterday. With the decline of radio, he primarily worked in television from the second half of the 1950s through the mid-1960s, including such series as The Detectives, Gunsmoke, Bonanza, The Untouchables, and The Fugitive, as well as Perry Mason. His casting in episodes of the latter created a situation that fans of the radio show appreciated for its ironic resonances. In at least one installment of Perry Mason, he was the defendant represented by television's Perry Mason, Raymond Burr. He was also the co-star of the Quinn Martin-produced series Twelve O'Clock High, as Major General Crowe, the direct superior officer to series protagonist Brigadier General Frank Savage (Robert Lansing), during the show's first season. Larkin didn't make his first feature film appearance until 1964, when John Frankenheimer cast him in Seven Days In May as Colonel Broderick, the antagonistic right-wing signal corps officer at the center of a conspiracy against the President of the United States. Although he was uncredited in the role, he had two memorable scenes with stars Kirk Douglas and Edmond O'Brien. He only ever got to work in two other movies, the Disney production of Those Calloways and John Sturges' The Satan Bug (both 1965); in the latter, he had one key scene. Larkin, who was known best for playing hard-nosed, authoritative types, died of a heart attack in early 1965 at the age of 52.

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: Helen Westcott launched her stage career at the age of 5. It has long been presumed that she made only one screen appearance in her preteen years, as a fairy in Midsummer Night's Dream (1935); in fact, she played a major role in the 1934 B western Thunder Over Texas, which starred Guinn "Big Boy" Williams. Be that as it may, Westcott would not achieve film prominence until the late 1940s--early 1950s, with such roles as Gregory Peck's ex-wife in The Gunfighter (1950) and the imperiled heroine of Dr. Jekyll and Mr. Hyde (1953). When her starring career in films faded, Helen Westcott turned to television, where she flourished as a character actress; her last screen appearance was as Mrs. Burrows in 1970's I Love My...Wife.

Trivia: Born into a poor San Francisco family, Raymond Bailey dropped out of school in the 10th grade to help make ends meet. He took on a variety of short-term jobs before escaping his lot by hopping a freight to New York. He tried in vain to find work as an actor, eventually signing on as a mess boy on a freighter. While docked in Honolulu, Bailey once more gave acting a try, and also sang on a local radio station. In Hollywood from 1932 on, Bailey took any nickel-and-dime job that was remotely connected to show business, but when World War II began, he once more headed out to sea, this time with the Merchant Marine. Only after the war was Bailey able to make a living as a character actor on stage and in TV and films. In 1962, he was cast as covetous bank president Milburn Drysdale on The Beverly Hillbillies, a role that made him a household name and one which he played for nine seasons (ironically, he'd once briefly worked in a bank during his teen years). After the show was cancelled in 1971, Bailey dropped out of sight and became somewhat of a recluse.

Trivia: American character actor Edward Platt is best remembered as the eternally exasperated Chief on the Get Smart series. Before making his screen debut in the mid-'50s, he worked as a singer for a band. In feature films, he was typically cast as generals and bosses.

Trivia: Character actor, onscreen from 1966.

Trivia: "I'm not a comic," insisted Mary Wickes. "I'm an actress who plays comedy." True enough; still Wickes was often heaps funnier than the so-called comics she supported. The daughter of a well-to-do St. Louis banker, Wickes was an excellent student, completing a political science degree at the University of Washington at the age of 18. She intended to become a lawyer, but she was deflected into theatre. During her stock company apprenticeship, Wickes befriended Broadway star Ina Claire, who wrote the young actress a letter of introduction to powerful New York producer Sam Harris. She made her Broadway debut in 1934, spending the next five seasons in a variety of characterizations (never the ingenue). In 1939, she found time to make her film bow in the Red Skelton 2-reeler Seein' Red. After a string of Broadway flops, Wickes scored a hit as long-suffering Nurse Preen (aka "Nurse Bedpan") in the Kaufman-Hart comedy classic The Man Who Came to Dinner. She was brought to Hollywood to repeat her role in the 1941 film version of Dinner. After a brief flurry of movie activity, Wickes went back to the stage, returning to Hollywood in 1948 in a role specifically written for her in The Decision of Christopher Blake. Thereafter, she remained in great demand in films, playing an exhausting variety of nosy neighbors, acerbic housekeepers and imperious maiden aunts. Though her characters were often snide and sarcastic, Wickes was careful to inject what she called "heart" into her portrayals; indeed, it is very hard to find an out-and-out villainess in her manifest. Even when she served as the model for Cruella DeVil in the 1961 animated feature 101 Dalmations, Cruella's voice was dubbed by the far more malevolent-sounding Betty Lou Gerson. Far busier on TV than in films, Wickes was a regular on ten weekly series between 1953 and 1985, earning an Emmy nomination for her work on 1961's The Gertrude Berg Show. She also has the distinction of being the first actress to essay the role of Mary Poppins in a 1949 Studio One presentation. Throughout the 1960s, 1970s and 1980s, Wickes did a great deal of guest-artist work in colleges and universities; during this period she herself went back to school, earning a master's degree from UCLA. Maintaining her professional pace into the 1990s, Wickes scored a hit with modern moviegoers as Sister Mary Lazarus in the two Sister Act comedies. Mary Wickes' final performance was a voiceover stint as one of the gargoyles in Disney's animated Hunchback of Notre Dame; she died a few days before finishing this assignment, whereupon Jane Withers dubbed in the leftover dialogue.
