Trivia: Redheaded leading man Robert Horton attended UCLA, served in the Coast Guard during World War II, and acted in California-based stage productions before making his entree into films in 1951. Horton's television career started off on a high note in 1955, when he was cast in the weekly-TV version of King's Row as Drake McHugh (the role essayed by Ronald Reagan in the 1942 film version). The series barely lasted three months, but better things were on the horizon: in 1957, Horton was hired to play frontier scout Flint McCullough in Wagon Train, which became the highest-rated western on TV. Horton remained with Wagon Train until 1962. He then did some more stage work before embarking on his third series, 1965's The Man Called Shenandoah. When this one-season wonder ran its course, Horton toured the dinner-theatre circuit, then in 1982 accepted a major role on the popular daytime soap opera As the World Turns. Horton continued acting until the late 1980s. He died in 2016, at age 91.

Trivia: A versatile, commanding, leathery character actor, he learned to raise and ride broncos on his family's ranch during his youth. He attended college for two years, became a seaman, then began his performing career as a radio announcer; he became nationally known as an announcer on the "March of Time" broadcasts. Onscreen from the late '40s, he often portrayed law officers; he was also convincing as a villain. He was well-known for his TV work; he starred in the series Naked City and Wagon Train. He was married to actress Jeanette Nolan, with whom he appeared in Saddle Tramp (1950) and Two Rode Together (1961); they also acted together on radio, and in the late '60s they joined the cast of the TV series The Virginian, portraying a married couple. Their son was actor Tim McIntire.

Trivia: Tall, straight-laced American actor Robert Culp parlayed his appearance and demeanor into a series of clean-cut character roles, often (though not always) with a humorous, mildly sarcastic edge. He was perhaps best known for three accomplishments: his turn as a Southern California documentary filmmaker who decides, along with his wife (Natalie Wood) to suddenly go counterculture with an "open marriage" in Paul Mazursky's Bob & Carol & Ted & Alice (1969); his iconic three-season role as an undercover agent in the espionage-themed series I Spy (1965-8); and his three-season run as Bill Maxwell on Stephen Cannell's superhero spoof series The Greatest American Hero (1981-3). Born in Oakland, California in 1930, Culp attended several West Coast colleges while training for a dramatic career. At 21, he made his Broadway debut in He Who Gets Slapped. Within six years, he was starring in his own Friday night CBS Western, Trackdown (1957-9) as Hoby Gilman, an 1870s era Texas Ranger. During the two-year run of this program, Culp began writing scripts, a habit he'd carry over to other series, notably The Rifleman and Gunsmoke. These all represented fine and noble accomplishments for a young actor, but as indicated, I Spy delivered a far greater impact to the young actor's career: it made Culp (along with his co-star, Bill Cosby) a bona fide celebrity. The men co-starred in the NBC adventure yarn as, respectively, Kelly Robinson and Alexander Scott, undercover agents involved in globetrotting missions for the U.S. government. Both actors brought to the program a sharp yet subtle sense of humor that (coupled with its exotic locations) made it one of the major discoveries of the 1965-6 prime-time line-up. During the second of I Spy's three seasons, Culp made his directorial debut by helming episodes of Spy; he went on to direct installments of several other TV programs. The success of Bob & Carol at the tail end of the 1960s proved that Culp could hold his own as a movie star, and he later directed and co-starred in 1972 theatrical feature Hickey and Boggs, which reunited him with Cosby, albeit to much lesser acclaim. Unfortunately, as the years rolled on, Culp proved susceptible to the lure of parts in B-pictures, such as Sky Riders (1976), Flood! (1976) and Hot Rod (1979), though he delivered a fine portrayal in television's critically-acclaimed Roots: The Next Generations (1979). Culp rebounded further with the semicomic role of CIA chief Maxwell on American Hero, but many now-infamous behind-the-scenes issues (and external issues, such as the shooting of Ronald Reagan) beleaguered that program and ended its run after only three seasons. In the years that followed, Culp vacillated between exploitation roles, in tripe such as Big Bad Mama 2 and Silent Night, Deadly Night 3, and more respectable, mainstream guest turns in television series including The Cosby Show and Murder, She Wrote. He enjoyed one of his most prestigious assignments with a supporting role in the big screen John Grisham-Alan Pakula thriller The Parallax View (1993), opposite Denzel Washington and Julia Roberts. In the years that followed, Culp's on-camera presence grew less and less frequent, though he did make a cameo in the 1996 Leslie Nielsen laugher Spy Hard. Television continued to provide some of Culp's finest work: he rejoined old friend Cosby for a 1994 I Spy TV-movie reunion and made guest appearances in such series as Lonesome Dove, Law & Order and The Dead Zone. Following a period of semi-retirement, Culp died suddenly and rather arbitrarily, when he sustained a head injury during a fall outside of his Hollywood home in March 2010. He was 79 years old.

Trivia: Open-faced, bulb-nosed character actor John Larch entered films in 1954, appearing mostly in westerns and outdoor adventures. During the "crime exposé" film cycle, Larch alternated between playing honest cops and dirty-palmed politicos. An old crony of actor/director Clint Eastwood, Larch appeared in such Eastwood efforts as Dirty Harry (1971) and Play Misty For Me (1972). His TV work has included weekly roles on two briefies of the 1960s, Arrest and Trial (1963) and Convoy (1965). Twilight Zone fans will instantly recognize John Larch as the walking-on-eggs father of malevolent telekinetic youngster Anthony Fremont (Billy Mumy) in the 1961 Zone chiller "It's a Good Life."

Trivia: The son of a Boston barber, Leonard Nimoy was a star at the age of 8, when he played Hansel in a children's theatre production of Hansel and Gretel. Nimoy remained with his local kiddie theater troupe until 16 (one of his directors during this period was Boris Sagal). After studying drama at Boston College and Antioch College, he took acting lessons from Jeff Corey at the Pasadena Playhouse. In films from 1950, Nimoy played the title character in the low-budget Kid Monk Baroni and essayed bits and minor roles in such productions as Zombies of the Stratosphere (1951), Rhubarb (1951) and Them! (1954). In between acting assignments, he held down a dizzying variety of jobs: soda jerk, newspaper carrier, vacuum-cleaner salesman, vending machine mechanic, pet-shop clerk, cabbie and acting coach. During his 18 months in Special Services at Fort McPherson, Georgia, he acted with Atlanta Theater Guild when he could spare the time. Back in Hollywood in 1956, he became virtually a regular at the Ziv TV studios, playing villains in programs like Highway Patrol and Sea Hunt. For a short while, he specialized in the plays of Jean Genet, appearing in both the stage and film productions of The Balcony and Deathwatch. Impressed by Nimoy's guest turn on a 1963 episode of The Lieutenant, producer Gene Roddenberry vowed to cast the saturnine, mellow-voiced actor as an extraterrestrial if ever given the chance. That chance came two years later, when Roddenberry signed Nimoy to play Vulcanian science officer Spock on Star Trek. At first pleased at the assignment, Nimoy came to resent the apparent fact that the public perceived him as Spock and nothing else: indeed, one of his many written works was the slim autobiography I Am Not Spock. After Star Trek's cancellation, Nimoy joined the cast of Mission: Impossible in the role of "master of disguise" Paris (he replaced the series' previous master of disguise Martin Landau, who ironically had originally been slated to play Spock). In the early 1970s, Nimoy began racking up directorial credits on such series as Night Gallery. He also made his first Broadway appearance in 1973's Full Circle. And, perhaps inevitably, he returned to Spock, thanks to the popular demand engendered by the then-burgeoning Star Trek cult. His initial reacquaintance with the role was as voiceover artist on the 1973 Saturday-morning cartoon version of Star Trek. Then Spock went on the back burner again as Nimoy devoted himself to his theatrical commitments (a touring production of Sherlock Holmes, his one-man show Vincent), his writing and directing activities, and his hosting chores on the long-running (1976-82) TV documentary series In Search Of.... Finally in 1978, Nimoy was back in his Enterprise uniform in the first of several Star Trek theatrical features. The Spock character was killed off in the second Trek picture The Wrath of Khan, but Nimoy stayed with the franchise as director of the next two feature-length Trek entries (PS: Spock also came back to life). He went on to direct such non-Trek filmic endeavors as 3 Men and a Baby (1987), The Good Mother (1988), Funny About Love (1990) and Holy Matrimony (1994). He also produced and acted in the 1991 TV movie Never Forget, and served as executive producer of the 1995 UPN network series Deadly Games. Perhaps because he will always have dozens of professional irons in the fire, Leonard Nimoy now seems resigned to being forever associated with the role that brought him international fame; his most recent autobiographical work was aptly titled I Am Spock. In 2009 he returned to his iconic role portraying Spock in J.J. Abrams smash-hit reboot of the Star Trek franchise. He next took on a recurring role in the sci-fi series Fringe, playing scientist William Bell. Nimoy made a final cameo appearance in Star Trek Into Darkness (2013). He died in 2015, at age 83.
