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: Born in Canada, he was brought up in New York City. For a while he was a professional swimmer in a water carnival. He became a stage actor, appearing in many productions in stock and on Broadway; he often appeared in Shakespeare. In the mid '40s he began working in films, at first in lead roles that tended to be introspective; as time went by, he was cast in secondary roles, often as a pessimistic bad guy. For his work in All the King's Men (1949) he received a Best Supporting Actor Oscar nomination. In the '60s his career began to dry up, and he appeared in many low-budget Italian films; however, he stayed busy as a screen actor into the '80s, often appearing in action or horror films. He co-directed and co-produced the film Outlaw Territory (1953). From 1949-56 he was married to actress Joanne Dru.

Trivia: The son of actors Harry Carey and Olive Golden, Harry Carey Jr. never answered to "Harry" or "Junior"; to his friends, family and film buffs, he was always "Dobe" Carey. Raised on his father's California ranch, the younger Carey spent his first six adult years in the Navy. While it is commonly assumed that he made his film debut under the direction of his dad's longtime friend John Ford, Carey in fact was first seen in a fleeting bit in 1946's Rolling Home, directed by William Berke. It wasn't until his third film, Three Godfathers (dedicated to the memory of his father) that Carey worked with Ford. Honoring his promise to Harry Sr. that he'd "look after" Dobe, Ford saw to it that the younger Carey was given a starring assignment (along with another of the director's proteges, Ben Johnson), in Wagonmaster (1950). Though he handled this assignment nicely, exuding an appealing earnest boyishness, Carey wasn't quite ready for stardom so far as the Hollywood "higher-ups" were concerned, so he settled for supporting roles, mostly in westerns. John Ford continued to use Carey whenever possible; in 1955's The Long Gray Line, the actor has a few brief scenes as West Point undergraduate Dwight D. Eisenhower. Carey was also featured on the "Spin and Marty" segments of Walt Disney's daily TVer The Mickey Mouse Club (1955-59). In later years, Carey's weather-beaten face was seen in choice character assignments in films ranging from The Whales of August (1987) to Back to the Future III (1990); he was also hired by such John Ford aficionados as Peter Bogdanovich, who cast Carey as an old wrangler named Dobie (what else?) in Nickelodeon (1976), and as an ageing bike-gang member named Red in Mask (1985). In 1994, Harry Carey Jr. published his autobiography, Company of Heroes. Carey died of natural causes at age 91 in late December 2012.

Trivia: Manhattan native Bartlett Robinson headed to Los Angeles in the mid-'30s for the express purpose of becoming a radio actor. He appeared in innumerable soap operas and anthologies, and starred as Erle Stanley Gardner's super-lawyer Perry Mason in a 1943 radio series. His stage credits on both coasts included Sweet River, Merchant of Yonkers, and Point of No Return. In films from 1956 to 1973, he was often cast as doctors and military officials. Bartlett Robinson's TV credits include the recurring roles of Willard Norton in Wendy and Me (1964) and Frank Campbell in Mona McCluskey (1965).

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: Supporting actor Martin West (born Martin Weixelbaum) has been appearing in feature films and on television since making his debut in Freckles (1960). In 1966, he became the fourth actor to play Dr. Brewer on the daytime soap opera General Hospital.

Trivia: James B. Sikking (the "B" stands for Barrie, as in James M. Barrie, his parents' favorite author) was active in student theatricals at the University of California-Santa Barbara, UCLA and the University of Hawaii. Sikking's first film was 1963's The Strangler; his subsequent movie work found him alternating between punkish villains and steely authority types. His earliest regular TV stint was as Dr. James Hobart, one of Rachel Ames' many amours, on the daytime drama General Hospital. If we bypass his brief stint as cosmetics executive Geoffrey St. James in the mercifully short-lived 1979 sitcom Turnabout, we can regard Lt. Howard Hunter on Hill Street Blues as Sikking's first recurring prime-time TV characterization. Looking like a cross between George C. Scott and Roy Scheider on both of their bad days, Lt. Hunter was Hill Street Station's gonzo SWAT team leader, eager to prove his worth by blowing a hole in anyone who looks at him cross-eyed. It is to Sikking's credit that he invested this initially two-dimensional character with depth and humanity, so much so that Hunter caused viewers' hearts to skip a beat or two when he attempted suicide in a 1984 episode. Sikking remained with H.S.B. until its cancellation in 1987, moving on to such assignments as "The Old Man" in the Jean Shepherd-inspired cable flick Ollie Hopnoodle's Haven of Bliss (1989). From 1989 to 1993, Sikking co-starred as Dr. David Howser, father of 16-year-old medical genius Neil Patrick Harris, on the weekly sitcom Doogie Howser MD. James B. Sikking's recent film credits include the pompous Captain Styles in Star Trek 3: The Search for Spock (1984) and FBI chief Denton Voglers in The Pelican Brief (1994).
