Trivia: The younger brother of Gunsmoke star James Arness, American actor Peter Graves worked as a musician and radio actor before entering films with 1950's Rogue River. At first, it appeared that Graves would be the star of the family, since he was cast in leads while brother Jim languished in secondary roles. Then came Stalag 17 (1953), in which Graves was first-rate as a supposedly all-American POW who turned out to be a vicious Nazi spy. Trouble was, Graves played the part too well, and couldn't shake the Nazi stereotype in the eyes of most Hollywood producers. Suddenly the actor found himself in such secondary roles as Shelley Winters' doomed husband in Night of the Hunter (1955) (he was in and out of the picture after the first ten minutes), while sibling James Arness was riding high with Gunsmoke. Dissatisfied with his film career, Graves signed on in 1955 for a network kid's series about "a horse and the boy who loved him." Fury wasn't exactly Citizen Kane, but it ran five years and made Graves a wealthy man through rerun residuals--so much so that he claimed to be making more money from Fury than his brother did from Gunsmoke. In 1966, Peter Graves replaced Steven Hill as head honcho of the force on the weekly TV adventure series Mission: Impossible, a stint that lasted until 1973. Though a better than average actor, Graves gained something of a camp reputation for his stiff, straight-arrow film characters and was often cast in films that parodied his TV image. One of the best of these lampoonish appearances was in the Zucker-Abrahams comedy Airplane (1980), as a nutty airline pilot who asks outrageous questions to a young boy on the plane (a part the actor very nearly turned down, until he discovered that Leslie Nielsen was co-starring in the film). Peter Graves effortlessly maintained his reliable, authoritative movie persona into the '90s and 2000s, and hosted the Biography series on A&E, for which he won an Emmy; he also guest-starred on programs including Cold Case, House and American Dad. Graves died of natural causes in March 2010, at age 83.

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.

Trivia: Fans of the original action /espionage series Mission Impossible (1966-70) may recognize black actor Greg Morris for playing electronics wizard Barney Collier. Morris spent most of his career on television, appearing on such shows as Ben Casey, The Dick Van Dyck Show and The Twilight Zone. During the 1970s, Morris was a regular on Vega$ (1978-81), playing police officer Lt. David Neslon. A native of Cleveland who spent part of his childhood in New York City, his mother worked as a secretary for black labor leader A. Phillip Reynolds. Before becoming a television actor during the early '60s, Morris attended Ohio State University and the University of Iowa. Morris passed away at the age of 61 on August 27, 1996. The cause of death was unreported.

Trivia: Veteran TV actor Jerry Douglas began his career on-screen in the early '60s, appearing on a multitude of shows like Mission: Impossible and Bonanza while supporting his family with a day job as an insurance salesman. He would sustain his career on these singular and often memorable appearances for over two decades before joining the cast of the daytime soap The Young and the Restless in 1985, playing patriarch John Abbott. He would remain with the show until 2008.

Trivia: British lead actress, onscreen from the early '60s.

Trivia: British actor Don Knight played leading roles in a number of Hollywood films between the late '60s and early '80s. He began acting while attending University in 1958 and later worked on television. Knight was also an ordained minister and a dialectician.

Trivia: A graduate of the University of Wisconsin, Vic Perrin's first significant stage credit was in the touring company of Helen Hayes' Victoria Regina. While working as a news announcer with the ABC radio network in the mid-'40s, he decided to return to acting, and within a few years was one of radio's busiest character players. He was one of the regulars on the long-running soap opera One Man's Family, and could also be heard on such prestigious anthologies as Escape and Suspense. He is most closely associated with the original radio versions of Dragnet and Gunsmoke, writing several scripts for the latter series. He continued his association with Dragnet creator Jack Webb into the TV versions of the 1950s and 1960s, playing a wide variety of kindly priests, two-bit crooks, soft-spoken detectives, suburban alcoholics, liberal professors, and homicidal maniacs. In films from 1952, he was seen as a publicity-seeking gunman in The Racket (1953), a gay art director in Forever Female (1956), and a bearded pedant in The Bubble (1969), among other films. A prolific voice-over specialist, Vic Perrin provided countless characterizations for such television cartoon series as Jonny Quest and Fantastic Four; he is perhaps best known for his two-year stint as the unseen Control Voice ("There is nothing wrong with your television set?") on TV's The Outer Limits (1963-1965).
