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: 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, onscreen from the '50s; he often played military men, sheriffs, or policemen.

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: Possessor of one of the meanest faces in the movies, American actor Ray Teal spent much of his film career heading lynch mobs, recruiting for hate organizations and decimating Indians. Naturally, anyone this nasty in films would have to conversely be a pleasant, affable fellow in real life, and so it was with Teal. Working his way through college as a saxophone player, Teal became a bandleader upon graduation, remaining in the musical world until 1936. In 1938, Teal was hired to act in the low-budget Western Jamboree, and though he played a variety of bit parts as cops, taxi drivers and mashers, he seemed more at home in Westerns. Teal found it hard to shake his bigoted badman image even in A-pictures; as one of the American jurists in Judgment at Nuremberg (1961), he is the only member of Spencer Tracy's staff that feels that sympathy should be afforded Nazi war criminals -- and the only one on the staff who openly dislikes American liberals. A more benign role came Teal's way on the '60s TV series Bonanza, where he played the sometimes ineffectual but basically decent Sheriff Coffee. Ray Teal retired from films shortly after going through his standard redneck paces in The Liberation of LB Jones (1970).

Trivia: A former pro baseball player, Bing Russell eased into acting in the 1950s, appearing mostly in westerns. Russell could be seen in such bonafide classics as The Horse Soldiers (1959) and The Magnificent Seven (1960), and not a few bow-wows like Billy the Kid vs. Dracula (1966). From 1961 through 1973, Russell played the semiregular role of Deputy Clem on the marathon TV western series Bonanza. When time permitted, he also dabbled in screenwriting. The father of film star Kurt Russell, Bing Russell has acted with his son on several occasions, most memorably in the role of Vernon Presley in the 1979 TV-movie hit Elvis.

Trivia: An alumnus of the Indiana University Law School, Herbert Vigran gave up the legal world to become an actor. Making his 1935 film debut in Vagabond Lady, Vigran had a few lean months after his first flurry of Hollywood activity, but began getting stage work in New York on the basis of a portfolio of photos showing him sharing scenes with several well-known movie actors (never mentioning that most of his film roles were bit parts). After his first Broadway success in Having Wonderful Time, Vigran returned to L.A., accepting small parts in movies while keeping busy with plenty of lucrative radio work; among his hundreds of radio assignments was the title character on the wartime sitcom "The Sad Sack." In films, the harsh-voiced, heavily eyebrowed Vigran could usually be seen as brash reporters and Runyon-esque hoodlums; his favorite role was the rumpled private eye in the 1954 Dick Powell/Debbie Reynolds comedy Susan Slept Here. During the 1950s, Vigran was most active in TV, essaying half a dozen bad guy roles on the Superman series and appearing regularly as Monte the Bartender on the Dante's Inferno episodes of the anthology series Four Star Playhouse. In the early '70s, Herb Vigran found time during his hectic movie and voice-over schedule to play the recurring role of Judge Brooker on Gunsmoke.

Trivia: Character actor, onscreen from 1937.

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.
