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: Hardcase leading man Howard Duff built his reputation on radio, where among several other assignments he was cast as Dashiell Hammett's two-fisted private eye Sam Spade. He made so vivid an impression in this role that, when cast in his first film Brute Force (1947), he was given special billing in the credits as "radio's Sam Spade." His burgeoning film career was slowed down in the early 1950s by the iniquities of the Hollywood Blacklist. Duff's no-nonsense image was softened into sitcom buffoonery when, in 1957, he was cast in TV's Mr. Adams and Eve. His co-star was his then-wife Ida Lupino, and the series' producer was Lupino's previous husband Collier Young. Ida was a frequent director for Duff's subsequent TV series Dante (1960), in which he more-or-less reprised his Sam Spade characterization. Duff's later TV assignments included a three-year starring stint on Felony Squad (1966-69) and supporting roles in the prime time serials Flamingo Road and Knot's Landing. In the 1970s, Howard Duff returned to filmmaking as a character actor, scoring critical successes with his roles as an eternally inebriated relative in Altman's A Wedding (1978) and as Dustin Hoffman's attorney in Kramer vs. Kramer (1979).

Trivia: Wisconsinite John Litel was a graduate of the University of Pennsylvania. When World War I broke out in Europe, Litel didn't feel like waiting until America became officially involved and thus joined the French army, serving valiantly for three years. Returning to America, Litel studied at the American Academy of Dramatic Arts and entered into the peripatetic world of touring stock companies. His first film was the 1929 talkie The Sleeping Porch, which starred top-hatted comedian Raymond Griffith. He settled in Hollywood for keeps in 1937, spending the next three decades portraying a vast array of lawyers, judges, corporate criminals, military officers, and even a lead or two. Litel was a regular in two separate "B"-picture series, playing the respective fathers of Bonita Granville and James Lydon in the Nancy Drew and Henry Aldrich series. On television, John Litel was appropriately ulcerated as the boss of Bob Cummings on the 1953 sitcom My Hero.

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 character actor Pat McVey had several seasons' worth of stage experience to his credit when he made his film bow in 1944. Though he seldom rose above the supporting player ranks onscreen, he had better luck on television. From 1950 to 1954 he starred as crusading newspaper editor Steve Wilson in the long-running TV series Big Town. Patrick McVey's later video assignments include the syndicated Western Boots and Saddles (1957) and the San Diego-based cop drama Manhunt (1959), in which he co-starred with Victor Jory.

Trivia: Chinese/American actor Victor Sen Yung would always be limited by stereotype in his selection of film roles, but it cannot be denied that he did rather well for himself within those limitations. Billed simply as Sen Yung in his earliest films, the actor was elevated to semi-stardom as Jimmy Chan, number two son of screen sleuth Charlie Chan. He first essayed Jimmy in 1938's Charlie Chan in Honolulu, replacing number one son Keye Luke (both Luke and Yung would co-star in the 1948 Chan adventure The Feathered Serpent). Not much of an actor at the outset, Yung received on-the-job training in the Chan films, and by 1941 was much in demand for solid character roles. With the absence of genuine Japanese actors during World War II (most were in relocation camps), Yung specialized in assimilated, sophisticated, but nearly always villainous Japanese in such films as Across the Pacific (1942). Remaining busy into the '50s, Yung co-starred in both the stage and screen versions of Rodgers and Hammerstein's Flower Drum Song. His longest-lasting assignment in the '60s was as temperamental cook Hop Sing on the TV series Bonanza. Victor Sen Yung died in his North Hollywood home of accidental asphyxiation at the age of 65.

Trivia: American actor Lane Bradford spent most of his film career in westerns - and in so doing carried on the tradition of his father, veteran sagebrush villain John Merton. Breaking into movies in bit parts, Bradford's first verified screen role was in 1946's Silver Range. He came a bit too late to flourish in B westerns (which died out in 1954), but Bradford essayed cowpoke roles, usually menacing in nature, until 1968. Once in a while, Bradford would venture far afield from the Old West - notably as the Martian villain Marex in the 1952 Republic serial Zombies of the Stratosphere. Lane Bradford retired to Hawaii shortly after completing his last film, Journey to Shiloh (1968).

Trivia: The son of actors, Percy Helton began his own career at age two in a Tony Pastor revue in which his parents were performing. The undersized Helton was a valuable juvenile player for producer David Belasco, making his film debut in a 1915 Belasco production, The Fairy and the Waif. Helton matured into adult roles under the stern guidance of George M. Cohan. After serving in the Army during World War I, Helton established himself on Broadway, appearing in such productions as Young America, One Sunday Afternoon and The Fabulous Invalid. He made his talkie debut in 1947's Miracle on 34th Street, playing the inebriated Macy's Santa Claus whom Edmund Gwenn replaces. Perhaps the quintessential "who is that?" actor, Helton popped up, often uncredited, in over one hundred succinct screen characterizations. Forever hunched over and eternally short of breath, he played many an obnoxious clerk, nosey mailman, irascible bartender, officious train conductor and tremulous stool pigeon. His credits include Fancy Pants (1950), The Robe (1953), White Christmas (1954), Rally Round the Flag Boys (1959), The Music Man (1962) and Hush Hush Sweet Charlotte (1965), as well as two appearances as sweetshop proprietor Mike Clancy in the Bowery Boys series. Thanks to his trademarked squeaky voice, and because he showed up in so many "cult" films (Wicked Woman, Kiss Me Deadly, Sons of Katie Elder), Helton became something of a high-camp icon in his last years. In this vein, Percy Helton was cast as the "Heraldic Messenger" in the bizarre Monkees vehicle Head (he showed up at the Monkees' doorstep with a beautiful blonde manacled to his wrist!), the treacherous Sweetieface in the satirical western Butch Cassidy and the Sundance Kid (1969), and the bedraggled bank clerk Cratchit on the TV series The Beverly Hillbillies.
