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: The son of a movie stunt man, Victor French made his screen entree in westerns, where his unkempt beard and scowling countenance made him a perfect heavy. He carried over his robbin' and rustlin' activities into television, making multiple appearances on such series as Gunsmoke and Bonanza. It was former Bonanza star Michael Landon, a great friend of French's, who "humanized" the veteran screen villain with the role of farmer Isiah Edwards in the weekly TV drama Little House on the Prairie. French temporarily left Little House in 1977 to star in his own sitcom, Carter Country, in which he played an affable Southern sheriff who tried his best to accommodate the ever-changing racial relationships of the 1970s. In 1984, Landon cast French as ex-cop Michael Gordon, whose bitterness at the world was softened by the presence of a guardian angel (Landon), in the popular TV series Highway to Heaven. French directed every third episode of this series, extending his directorial activities to the Los Angeles theatre scene, where he won a Critics Circle award for his staging of 12 Angry Men. In contrast to his earlier bad-guy roles, French went out of his way in the 1980s to avoid parts that required him to exhibit cruelty or inhumanity. Victor French died in 1989, shortly after completing work on the final season of Highway to Heaven.

Trivia: Herschel Bernardi, along with his actor-brother Jack, was the product of a long-established family of Yiddish performers. On stage from childhood, Bernardi made his first on-camera appearances in a brace of Yiddish-language films, Green Fields and Yankel the Blacksmith, both lensed in New Jersey in 1939. While successful in ethnic productions, Herschel encountered resistance from producers of mainstream Broadway plays, one of whom advised the actor to wait until he "grew into" his character-actor face. As Harold Bernardi, he played a bit in the 1945 Hollywood film Miss Susie Slagle's. He was one of several actors blacklisted for their alleged leftist politics in the 1950s, an experience he relived as a cast member of the 1976 film The Front. Shortly after being "exonerated," Bernardi was cast in the recurring role of Lt. Jacoby on the late-1950s series Peter Gunn, an assignment for which he won an Emmy. In 1969, Bernardi played the starring part of a blue-collar worker thrust into the executive pool in the TV sitcom Arnie. He also provided voiceovers for hundreds of cartoons and commercials, "starring" as Charley the Tuna and the Jolly Green Giant. On Broadway in the 1960s and '70s, Herschel Bernardi starred in over 700 performances of Fiddler on the Roof and also played the lead in the musical Zorba; at one juncture, Bernardi had so strained his vocal chords that he was ordered by his doctor not to speak for a full year, lest he permanently lose his voice.

Trivia: Mark-Paul Gosselaar became a TV teen idol as bleached-blond Zack on Saved by the Bell and spent the latter half of the 1990s trying to live down that legacy. Born in California to Dutch parents, Gosselaar had already made numerous TV guest appearances as a child actor by the time he was cast on Saved by the Bell in 1989. Though the perky high school/college sitcom made him a hit with the young audience, he had difficulties finding work after leaving the show in 1994. Still, he managed to land roles in TV and B-films, including Sticks and Stones (1996), Kounterfeit (1996), and the Western Brothers of the Frontier (1996). Confirming that his teen (and perhaps teen idol) years were behind him, Gosselaar played a college date rapist in She Cried No (1996) and co-starred with Hilary Swank in the college hazing TV movie Dying to Belong (1997). Moving to higher profile feature films, Gosselaar engaged in slightly more lighthearted college hijinks in MTV Films' black comedy Dead Man on Campus (1998). He was back on TV, however, playing young adults in two short-lived drama series, Hyperion Bay (1998) and D.C. (2000). In 2001, Gosselaar was finally able to truly graduate from Saved by the Bell to bona-fide grown-up roles when he was selected to take over for Rick Schroeder on the long-running gritty cop series NYPD Blue. His four year run with the series cemented the actor's new reputation as an adult actor, and he would go on to star on several other shows, like Commander in Chief, Raising the Bar, and Franklin & Bash. In 2015, secure in his adult career, Gosselaar reunited with some of his Saved By the Bell cast members for a skit on The Tonight Show.
