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: Muscular leading man Ed Nelson started out as a member of quickie-filmmaker Roger Corman's stock company, appearing in such drive-in fodder as Hot Rod Girl (1956), Invasion of the Saucer Men (1957) and Cry Baby Killer. In these and other low-budgeters of the late 1950s, Nelson not only starred, but doubled on the technical crew: he was one of several production assistants portraying the title crustacean in The Attack of the Crab Monsters (1956), and designed and operated the parasite props in 1958's The Brain Eaters, which he also produced. Eventually outgrowing such things, Nelson rose to TV stardom as Dr. Michael Rossi on the prime time soap opera Peyton Place, which ran from 1964 through 1969. He later starred as Ward Fuller on The Silent Force (1970) and as Dr. Michael Wise in Doctor's Private Lives (1979). In 1969, Nelson hosted a daily, syndicated talk show, which he was ultimately forced to give up when he decided to enter politics ("conflict of interests" and "equal time" were still considerations back then). He played President Truman several times, including the 1980 TV movie Enola Gay: The Men, the Mission, the Atomic Bomb, in the 1992 Brooke Shields flick Brenda Starr and onstage in Give 'Em Hell, Harry. Nelson died in 2014 at age 85.

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: 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: Best described as a young George Kennedy type (though he and Kennedy were contemporaries), American actor Mort Mills spent three decades playing omniprescent and menacing types. He started out in films in the early '50s, showing up briefly in such productions as Affair in Trinidad (1952) and Farmer Takes a Wife (1955). He also seemed to be lurking in the background, taking in the information at hand and waiting to saunter over and pounce upon someone smaller than himself (which was just about everyone). Mills' character straddled both sides of the law: He was a friendly frontier sheriff in the 1958 syndicated TV western Man without a Gun and a less friendly police lieutenant on the 1960 network adventure weekly Dante; conversely, he was vicious western gunslinger Trigger Mortis in the 1965 Three Stooges feature The Outlaws is Coming. Mort Mills' most indelible screen moments occured in Hitchcock's Psycho (1960), wherein he portrayed the suspicious highway patrolman who almost catches embezzler Janet Leigh; had he succeeded, she would have spent the night in the pokey rather than the Bates Motel.

Trivia: Character actor Bill Quinn specialized in playing wise or fatherly roles on stage, screen, and television. A native of New York City, Quinn was five when he became a professional vaudevillian. After many years on stage, he joined Orson Welles' Mercury Playhouse radio troupe. Quinn made his film debut with a small supporting role in the circus drama The Flying Fontaines (1959). His film career continued steadily through the mid-'70s, then slowed down to about a film every two or three years. He made his final big-screen appearance playing the father of Dr. McCoy in Star Trek V: The Final Frontier. He appeared numerous times on television. Between 1958 and 1963, he played bartender Sweeney on The Rifleman and in All in the Family and its spin-off, Archie Bunker's Place, Quinn played barfly Mr. Van Ranesleer. His other TV credits include guest star appearances in series, miniseries, and made-for-TV movies.

Trivia: Although not as remembered as Yakima Canutt or even Cliff Lyons, brawny George DeNormand became one of the founding fathers of modern movie stunt work. In films from the early '30s, DeNormand performed stunts and played bit roles in scores of action thrillers, B-Westerns, and serials, working mostly for that memorable factory of thrills, Republic Pictures. His career lasted well into the television era and he was especially visible on such shows as The Cisco Kid, Range Rider, and Sky King. Married to writer/director Wanda Tuchock (1898-1985), DeNormand spent his last years at the Motion Picture Country House and Hospital in Woodland Hills, CA.

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: Gaunt, hollow-eyed character actor Wilbur Mack spent his first thirty years in show business as a vaudeville headliner. With his first wife Constance Purdy he formed the team of Mack and Purdy, and with second wife Nella Walker he trod the boards as Mack and Walker. In films from 1925 to 1964, he essayed innumerable bits and extra roles, usually playing doormen or cops. Mack also appeared in a number of "Bowery Boys" comedies.
