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: Character actor Richard O'Brien was born in Fargo, ND, in 1917, far away from the bright lights of Hollywood. He didn't begin acting until the age of 46, when he began making appearances on numerous TV shows, from Family Affair to The Fugitive, often coming back to make subsequent appearances on the same show, but playing different characters. O'Brien's ability to take on a new persona so convincingly would keep him in steady work for decades to come, until his death in 1983 at the age of 66.

Trivia: Big-framed character actor (and sometime leading man) David Huddleston worked in virtually every film and television genre there is, from Westerns to crime dramas to science fiction. Born in Vinton, Virginia, he attended the Fork Union Military Academy before entering the United States Air Force, where he received a commission as an officer. After returning to civilian life, Huddleston enrolled in the American Academy of Dramatic Arts. He made his television debut in 1961, at age 31, in an episode of the Western series Shotgun Slade. Two years later, the actor made his first big-screen appearance with a small role in All the Way Home (1963). A year later, he showed up in Black Like Me; and in 1968, Huddleston was back on the big screen in the thriller A Lovely Way to Die. He got considerably busier in the years that followed, mostly on television series such as Adam 12, Then Came Bronson, and Room 222, in roles of ever-increasing size. These were broken up by the occasional film job, of which the most notable at the time was the part of the comically helpful town dentist in Howard Hawks' Western Rio Lobo (1970), which gave Huddleston some extended (and humorous) screen-time alongside John Wayne. At the time, his feature-film work was weighted very heavily toward Westerns, while on television Huddleston played everything from service-station attendants to teachers to devious executives, primarily in crime shows. With his deep voice and prominent screen presence, plus a sense of humor that never seemed too far from his portrayals -- even of villains -- Huddleston was one of the busier character actors of the 1970s. Indeed, 1974 comprised a year of credits that any actor in the business could envy: John Wayne used Huddleston in McQ, one of the aging star's efforts to get away from Westerns, but Huddleston was back doing oaters in Billy Two Hats and aided Mel Brooks in parodying the genre in Blazing Saddles (all 1974). As comical as Huddleston could be, he could play sinister equally well, as he proved in Terence Young's The Klansman (1974) -- and that doesn't even count his television roles. By the end of the 1970s, he had graduated to a starring role in the series Hizzoner (1979), about a small-town mayor; and in the 1980s he had recurring roles in series such as The Wonder Years. Huddleston's big-screen breakthrough came with the title role in Santa Claus: The Movie (1985), and he became a ubiquitous figure on the small screen with a series of orange-juice commercials. His subsequent big-screen appearances included Frantic (1988) and The Big Lebowski (1998), playing the title character, and he continued working into the first decade of the 21st century. In 2004, Huddleston essayed one of the most interesting and challenging roles of his screen career, in the short film Reveille. Working without dialogue alongside James McEachin (with whom he'd previously worked in the series Tenafly), he helped tell the story of a sometimes comical, ultimately bittersweet rivalry between two veterans of different armed services. Huddleston died in 2016, at age 85.

Trivia: American actor Walter Barnes was what was described by casting directories as an "outdoor action type." His first regular TV work was as Finn on 1959's Tales of the Vikings, a Kirk Douglas-produced syndicated series filmed in the German Alps. Remaining in Europe, Barnes continued to work swashbucklers like Captain Sinbad (1963) and westerns like Frontier Hellcat (1966) and The Big Gundown (1968). He returned to America in the late 1960s, where he was featured in such westernized productions as John Wayne's Cahill: US Marshal (1970), The Travelling Executioner (1972), Mackintosh and J.J. (1975), and Clint Eastwood's High Plains Drifter (1973) (as Sheriff Sam Shaw) and Broncho Billy (1980). Walter Barnes was as sturdy and steadfast as ever in 1981, when he appeared as the father of sheriff Buford Pusser (Bo Svenson) on the weekly TV version of Walking Tall.

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: The son of actor John Carradine, Keith Carradine began his own theatrical training at Colorado State University, dropping out after one semester because he felt he wasn't getting anywhere. Soon afterward, Carradine made his stage debut in the "tribal love rock musical" Hair; his brief relationship with fellow cast member Shelley Plimpton resulted in a daughter, Martha Plimpton, who grew up to become a prominent actress in her own right. Carradine's first film was 1971's McCabe and Mrs. Miller, directed by Robert Altman. Four years later, Carradine's musical composition "I'm Easy," which he performed in Altman's Nashville (1975), won an Academy Award. Carradine divested himself of his familiar movie mannerisms in the early 1990s to portray the folksy, gum-chewing title character in the Broadway hit The Will Rogers Follies. In 1995, he emulated the past screen villainy of his father and his brother, David, as the smirking antagonist of the movie melodrama The Ties That Bind. He continued to work in film and television throughout the rest of the decade, showing up in movies like A Thousand Acres (1997) and various TV series. Meanwhile, the early 2000s found Carradine as busy as ever, with a recurring role as Wild Bill Hickock (whom he had previously played in the 1995 feature WIld Bill) on HBO's popular wild west series Deadwood, as well as roles on Dexter, Dollhouse, and Damages serving well to keep him in the public eye. Always handy with a six-shooter, Carradine took aim at some particularly nasty extraterrestrials in Iron Man director Jon Favreau's sci-fi/western genre mash-up Cowboys and Aliens in 2011.

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.
