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: Canadian-born actor Stacy Harris was a fixture on American radio and television for decades, with occasional movie roles breaking up those small-screen engagements. Born in Big Timber, Quebec in 1918, he turned to acting full-time after the Second World War. With his authoritative voice, he was a natural for heroic roles and established himself on radio with an eight-year stint on This Is Your FBI. His big-screen debut came in 1951 in Appointment With Danger, an Alan Ladd starring vehicle in which one of the other key players was Jack Webb who, at the time, was also doing his show Dragnet on the radio and about to bring it to television. Harris became a memorable presence in the Dragnet stock company, appearing four times in the series' original 1950s run, as well as in the 1954 feature film of the same name -- these were interspersed with work in hundreds of television episodes across the 1950s and early 1960s. It was in the revived 1960s Dragnet series, however, that he got some of his best screen time, dividing his portrayal between portrayals of criminals and those on the side of the law -- in the former capacity, with his courtly good looks, finely chiseled features and authoritative voice, all a little reminiscent of an older Robert Ryan, he was a regular reminder to viewers that not all criminals look like or comport themselves as criminals. His best work of the series, however, was the last episode in which he appeared, "Forgery: The Ranger." The role of Clifford Ray Owens aka Barney Regal was a tour-de-force for the actor, playing a felon (who was, astoundingly, masquerading as a forest ranger) who is driven as much by serious psychiatric problems as greed. In 25 minutes of screen time, Harris dominates every moment and evokes a huge range of emotions, including sympathy and pity, which was unusual in the writing approach of the series.Harris appeared regularly in Webb's other series in the years before his death in 1973, at age 54.

Trivia: The son of a Pennsylvania minister, actor Cameron Mitchell first appeared on Broadway in 1934, in the Lunts' modern-dress version of Taming of the Shrew. He served as a bombardier during World War II, and for a brief period entertained thoughts of becoming a professional baseball player (he allegedly held an unsigned contract with the Detroit Tigers until the day he died). Mitchell was signed to an MGM contract in 1945, but stardom would elude him until he appeared as Happy in the original 1949 Broadway production of Death of the Salesman. He re-created this role for the 1951 film version, just before signing a long-term contract with 20th Century Fox. Throughout the 1950s, Mitchell alternated between likeable characters (the unpretentious business executive in How to Marry a Millionaire [1952]) and hissable ones (Jigger Craigin in Carousel [1956]); his best performance, in the opinion of fans and critics alike, was as drug-addicted boxer Barney Ross in the 1957 biopic Monkey on My Back. Beginning in the 1960s, Mitchell adroitly sidestepped the IRS by appearing in dozens of Spanish and Italian films, only a few of which were released in the U.S. He also starred in three TV series: The Beachcomber (1961), The High Chapparal (1969-1971), and Swiss Family Robinson (1976). Mitchell spent the better part of the 1970s and 1980s squandering his talents in such howlers as The Toolbox Murders, though there were occasional bright moments, notably his performance as a neurotic mob boss in 1982's My Favorite Year. A note for trivia buffs: Cameron Mitchell also appeared in the first CinemaScope film, The Robe (1953). Mitchell was the voice of Jesus in the Crucifixion scene.

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: Stoutly proportioned yet dignified character actor Howard Wendell was known for his skill and reliability in a screen career lasting three decades -- according to his grandson, he was referred to by those who knew his work as "one-take Wendell." Born Howard David Wendell in Johnstown, Pennsylvania in 1908, though he considered Elyria, Ohio, where he was raised, to be his home. His acting career began with work in a minstrel show, and he later appeared on a radio show broadcast out of Cleveland, Ohio. Wendell worked with the Elyria Playmakers, and was later an apprentice at the Cleveland Playhouse. Later, while traveling across the midwest as an actor, he also began directing plays and acting in summer stock, and subsequently moved on to road show productions in the northeast. By the end of the 1940s, he'd amassed some Broadway credits as well, and made his small-screen debut on Colgate Theatre. By 1952, he was in Hollywood and working in feature films, most notably Fritz Lang's The Big Heat (1953). Wendell proved adept at older character parts, including politicians, doctors, business executives, judges, and other authority figures -- in Lang's film, he was memorable as an incompetent and crooked police chief, who is seen harassing the honest members of his force and kowtowing to his city's worst gang elements. Perhaps Wendell's strangest appearance was in Edward L. Cahn's The Fourt Skulls of Jonathan Drake (1958), in which he portrayed a medical doctor whose skill at saving lives gets him killed -- his character appears, decidedly postmortem, in the guise of a severed head in the vault of the villain. Wendell could also do comedy, and appeared in his share of sitcoms, including The Dick Van Dyke Show. Although he officially retired in 1963, Wendell went on to do appearances in episodes of I Dream of Jeannie Batman in the later 1960s, and he gave his final screen performance on an episode of Adam-12 in 1971.

Trivia: Well-muscled former 1935 New York City heavyweight boxing champ Mickey Simpson was typically cast as a villain in numerous low-budget actioners, adventures, and Westerns of the '40s, '50s, and '60s. Before making his screen debut with a bit part in Stagecoach, Simpson had been Claudette Colbert's personal chauffeur. He served with the military during WWII and then returned to Hollywood to continue his busy onscreen career.

Trivia: A stage actor since the 1920s, Kenneth MacDonald found the going rough in Hollywood until he published and distributed a pamphlet titled "The Case of Kenneth MacDonald." This little self-promotional book brought him to the attention of studio executives, and throughout the 1930s MacDonald could be seen as a mustachioed, mellifluous-voiced villain in scores of westerns and melodramas. His work in the Charles Starrett westerns at Columbia led to a lengthy association with that studio. From 1940 through 1954, MacDonald played featured roles in such Columbia productions as Island of Doomed Men (1940), Power of the Whistler (1945) and The Caine Mutiny (1954); he was also prominently cast in the studio's short subjects, especially in the comedies of the Three Stooges and Hugh Herbert, his most familiar role being that of a society criminal or shyster lawyer. During the 1960s, Kenneth MacDonald was a semi-regular on the Perry Mason TV series, playing a solemn judge.

Trivia: Dour, lantern-jawed character actor John Anderson attended the University of Iowa before inaugurating his performing career on a Mississippi showboat. After serving in the Coast Guard during World War II, Anderson made his Broadway bow, then first appeared on screen in 1952's The Crimson Pirate. The actor proved indispensable to screenwriters trafficking in such stock characters as The Vengeful Gunslinger, The Inbred Hillbilly Patriarch, The Scripture-Spouting Zealot and The Rigid Authority Figure. Anderson's many screen assignments included used-car huckster California Charlie in Psycho (1960), the implicitly incestuous Elder Hammond in Ride the High Country (1962), the title character in The Lincoln Conspiracy (1977) and Caiaphas in In Search of Historic Jesus (1980). A dead ringer for 1920s baseball commissioner Judge Kenesaw Mountain Landis, Anderson portrayed that uncompromising gentleman twice, in 1988's Eight Men Out and the 1991 TV biopic Babe Ruth. A veteran of 500 TV appearances (including four guest stints on The Twilight Zone), John Anderson was seen as FDR in the 1978 miniseries Backstairs in the White House, and on a regular basis as Michael Spencer Hudson in the daytime drama Another World, Virgil Earp in The Life and Legend of Wyatt Earp (1955-61) and the leading man's flinty father in MacGiver (1985-92).
