Trivia: American actress Nancy Malone began appearing in films in 1956, and three years later landed her first weekly TV series assignment in The Naked City. Stardom came her way in 1965, when she was cast as Clara Varner in the short-lived TV version of The Long Hot Summer. Eventually she phased out acting to concentrate on producing (through her own Lilac Productions) and directing. Nancy Malone's producer credits include the 1976 TV movie Sherlock Holmes in New York; her directorial manifest includes individual episodes of TV's Touched By an Angel. Her last acting role was in 1985, but she continued producing and directing until her death in 2014, at age 79.

Trivia: Although his career stretches back half a century and includes over 100 films and countless TV programs, Leslie Nielsen gained true fame late in his career, when he starred in a series of comic spoofs beginning with 1980's Airplane!.The son of a Canadian Mountie and the brother of Canada's future Deputy Prime Minister, Nielsen was born in Regina, Saskatchewan, on February 11, 1926. He developed an early knack for acting when he was forced to lie to his disciplinarian father in order to avoid punishment, and he went on to become a radio announcer after serving in the Royal Canadian Air Force during WWII (despite being legally deaf, the result of a childhood illness). To prepare himself for his future career, Nielsen studied at Toronto's Academy of Radio Arts, which was run by CBC commentator and future Bonanza star Lorne Greene. After several years in radio, he won a scholarship to New York's Neighborhood Playhouse, where he studied acting under Sanford Meisner and dance under Martha Graham. He then spent five years appearing on such live television programs as Tales From Tomorrow before making his film bow in Ransom! (1956). With the exception of his starring roles in the sci-fi classic Forbidden Planet (1956) and the popular Debbie Reynolds-vehicle Tammy and the Bachelor (1957), much of Nielsen's early work was undistinguished; he was merely a handsome leading man in an industry overstocked with handsome leading men. An attempt to do a "Davy Crockett" by starring as Francis Marion in the Disney TV saga The Swamp Fox resulted in a nifty title tune but little else. Nielsen went on to star in such series as The New Breed, Bracken's World, and Hawaii Five-O (1968), but found he was more in demand as a heavy than as a hero.A notorious offscreen practical joker and cut-up, Nielsen was not given an onscreen conduit for this trait until he was cast in the Zucker-Abrahams-Zucker spoof Airplane (1980). This led to his deadpan characterization of monumentally inept police lieutenant Frank Drebin on Z.A.Z.'s cult TV series Police Squad, which in turn spawned the 1988 hit The Naked Gun and two sequels. Nielsen also found success in a number of other film spoofs, so much, in fact, that those familiar only with his loopy comedy roles are invariably surprised that, once upon a time, he took himself deadly seriously in films like Harlow (1965) and The Poseidon Adventure (1972). Nielsen died at the age of 84, of pneumonia, in late November 2010.

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: 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: For over 30 years, Paul Lambert played character roles on stage, screen, and television. He started out on the Manhattan stage in the early '50s. He also launched his television career around that time, appearing in series through the '80s ranging from Playhouse 90 to Hogan's Heroes to Doogie Howser, M.D.. Lambert died of cancer on April 27, 1997, at age 74.

Trivia: When diehard American movie fans speak of Jack Lambert, they are generally not referring to the British character actor of that name, but of the New York-born supporting player who was most often seen in gangster roles. Following Broadway experience, Lambert came to Hollywood in 1943, to menace Kay Kyser in the MGM musical comedy Swing Fever. Usually a secondary bad guy, Lambert was the main menace -- a scarfaced thug with a hook for a hand -- in Dick Tracy's Dilemma (1947). A less malevolent Jack Lambert was seen on a weekly basis as Joshua on the 1959-60 TV adventure series Riverboat.

Trivia: American character actor Douglas Henderson shifted his activities from stage to screen in 1952, when he appeared in Stanley Kramer's Eight Iron Men. Like many general purpose actors of the era, he was frequently cast in science fiction and horror films along the lines of King Dinosaur and Invasion of the Saucer Men. He was generally cast in authoritative or military roles: officers, congressmen, FBI agents, and the like. Douglas Henderson's final film assignment was the 1970 thriller Zigzag; eight years later, he committed suicide via carbon monoxide poisoning.

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.
