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: Famed for his ratchety voice and cold-fish stare, William Demarest was an "old pro" even when he was a young pro. He began his stage career at age 13, holding down a variety of colorful jobs (including professional boxer) during the off-season. After years in carnivals and as a vaudeville headliner, Demarest starred in such Broadway long-runners as Earl Carroll's Sketch Book. He was signed with Warner Bros. pictures in 1926, where he was briefly paired with Clyde Cook as a "Mutt and Jeff"-style comedy team. Demarest's late-silent and early-talkie roles varied in size, becoming more consistently substantial in the late 1930s. His specialty during this period was a bone-crushing pratfall, a physical feat he was able to perform into his 60s. While at Paramount in the 1940s, Demarest was a special favorite of writer/director Preston Sturges, who cast Demarest in virtually all his films: The Great McGinty (1940); Christmas in July (1940); The Lady Eve (1941); Sullivan's Travels (1942); The Palm Beach Story (1942); Hail the Conquering Hero (1944); Miracle of Morgan's Creek (1944), wherein Demarest was at his bombastic best as Officer Kockenlocker; and The Great Moment (1944). For his role as Al Jolson's fictional mentor Steve Martin in The Jolson Story (1946), Demarest was Oscar-nominated (the actor had, incidentally, appeared with Jolie in 1927's The Jazz Singer). Demarest continued appearing in films until 1975, whenever his increasingly heavy TV schedule would allow. Many Demarest fans assumed that his role as Uncle Charlie in My Three Sons (66-72) was his first regular TV work: in truth, Demarest had previously starred in the short-lived 1960 sitcom Love and Marriage.

Trivia: By the time she first appeared as Grandma Walton in 1971, American actress Ellen Corby had been playing elderly characters for nearly thirty years--and she herself was still only in her fifties. The daughter of Danish immigrants, Ellen Hansen was born in Wisconsin and raised in Philadelphia; she moved to Hollywood in 1933 after winning several amateur talent shows. Her starring career consisted of tiny parts in low-budget Poverty Row quickies; to make a living, Ellen became a script girl (the production person responsible for maintaining a film's continuity for the benefit of the film editor), working first at RKO and then at Hal Roach studios, where she met and married cameraman Francis Corby. The marriage didn't last, though Ellen retained the last name of Corby professionally. While still a script girl, Ellen began studying at the Actors Lab, then in 1944 decided to return to acting full time. She played several movie bit roles, mostly as servants, neurotics, and busybodies, before earning an Oscar nomination for the role of Trina the maid in I Remember Mama (1948). Her career fluctuated between bits and supporting parts until 1971, when she was cast as Grandma Walton in the CBS movie special The Homecoming. This one-shot evolved into the dramatic series The Waltons in 1972, with Ms. Corby continuing as Grandma. The role earned Ellen a "Best Supporting Actress" Emmy award in 1973, and she remained with the series until suffering a debilitating stroke in 1976. After a year's recuperation, Ellen returned to The Waltons, valiantly carrying on until the series' 1980 cancellation, despite the severe speech and movement restrictions imposed by her illness. Happily, Ellen Corby endured, and was back as Grandma in the Waltons reunion special of the early '90s.

Trivia: American singer and character actor Howard Wright was best known for starring in stage musicals following WWI. Much later, he began performing on radio, television, and in movies of the '50s and '60s.

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: In films from 1938's Tenth Avenue Kid, American actor Paul Bryar remained a durable character player for over thirty years, usually in police uniform. Among his screen credits were Follow Me Quietly (1949), Dangerous When Wet (1952), Inside Detroit (1955) and The Killer is Loose (1956). He also showed up in one serial, Republic's Spy Smasher (1942), and was a regular in Hollywood's B factories of the 1940s (he made thirteen pictures at PRC Studios alone, three of them "Michael Shayne" mysteries). Television took advantage of Bryar's talents in a number of guest spots, including the unsold pilot The Family Kovack (1974). He had somewhat better job security as a regular on the 1965 dramatic series The Long Hot Summer, playing Sheriff Harve Anders, though he and everyone else in the cast (from Edmond O'Brien to Wayne Rogers) were back haunting the casting offices when the series was cancelled after 26 episodes. One of Paul Bryar's last screen appearances was as one of the card players (with future star Sam Elliott) in the opening scene of Butch Cassidy and the Sundance Kid (1969).

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.

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: Yet another country & western music performer turned B-Western bit player, mustachioed Al Haskell and his accordion joined Johnny Luther, Chuck Baldra, Jack Jones and, to the regret of his fans, a singing Ken Maynard in Honor of the Range (1934), and later performed with Oscar Gahan and Rudy Sooter in Roy Rogers' Frontier Pony Express (1939). As an actor, Haskell would appear in nearly 100 B-Westerns and serials, almost always unbilled and often playing a henchman. His screen career lasted well into the 1950s.
