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: Perhaps the most definitive descriptor for Kiefer Sutherland's career is not any particular niche he's carved for himself, but rather his versatility. From the perfected subtleties he has portrayed in supporting roles, to his command of the screen as a star, Sutherland has covered abundant ground. His roles have ranged from deeply psychological, such as the medical student in Flatliners, to upbeat and authoritative, like the sheriff in Picking Up the Pieces. In addition to his talent on the big screen, Sutherland has earned directorial credits, as well as a Golden Globe Award in 2001 for Best Actor in a TV Drama.Kiefer Sutherland and his twin sister, Rachel, were born to acting parents Donald Sutherland and Shirley Douglas in the U.K. on December 21, 1966. In 1971, his parents divorced, and Sutherland moved from their home in L.A. to Toronto with his mother. Just six years later, he was appearing in theatrical performances, including a production of Throne of Strow. His first film appearance occurred in 1983, in Max Dugan Returns, with a scene featuring Sutherland alongside his father Donald Sutherland.The 1980s brought the beginning of what would become Kiefer Sutherland's lengthy list of film credits. Most notable were his roles in The Bay Boy -- a 1930s coming-of-age story set in Nova Scotia -- for which he won a Genie Award in 1984, and the Rob Reiner drama Stand by Me (1986) in which he played a scene-stealing bully. He appeared in The Lost Boys in 1987, also starring Jason Patric. In 1988, at age 20, Sutherland married Camelia Kath, who was 14 years his senior, and the couple had a daughter named Sarah Jude that same year. The marriage lasted for two years.Flatliners, 1990's groundbreaking psychodrama, starred Sutherland with Kevin Bacon, William Baldwin, and Julia Roberts. The story involved four medical students experimenting with death, attempting to actually die to experience the after-life, and then be revived by their peers. The unique story line and strong performances earned the stars a lot of attention for the film. Sutherland and Roberts engaged in an offscreen romance, which endured for some time after shooting had wrapped.In 1992, Sutherland starred in the blockbuster A Few Good Men, also starring Tom Cruise, Jack Nicholson, Demi Moore, and Kevin Bacon. Within a year, he made his directorial debut with the made-for-television drama Last Light, in which he also starred as a prison inmate. He was married a second time, to Kelly Winn, in 1996, but the relationship had ended by 2000.In the late '90s, his career picked up pace, with multiple acting and directing credits occurring within single years. The year 1997 featured Sutherland as Joey in a modern film noir called The Last Days of Frankie the Fly, and as director of the psycho-thriller Truth or Consequences, N.M. In A Soldier's Sweetheart, adapted from a story by Vietnam-vet writer Tim O'Brien, he played the narrator of the flashbacks, in 1998. That same year, he starred in the science fiction-mystery film Dark City with Jennifer Connelly and Rufus Sewell. His second self-directed TV movie, Woman Wanted, was one of four projects released crediting his name in 1999. He also appeared in a German film called After Alice, the psychotic drama Ground Control with Kristy Swanson and Kelly McGillis, and the thriller The Break Up starring Bridget Fonda.Shifting gears from the deep, psychosomatic, and eerie tones of his late-'90s films, Sutherland played the sheriff in 2000's Picking Up the Pieces. Featuring David Schwimmer, Cheech Marin, and Sharon Stone, the film was a satirical comedy infused with screwball humor, with a notable appearance by Woody Allen. Again revisiting a more dramatic genre, Sutherland starred in Fox's revolutionary action series 24 as antiterrorism agent Jack Bauer. With each 1-hour episode told in real time, the 24 episode season represented a single day in the show's chronology. Immediately garnering rave reviews and a rabid core fanbase, the series became a hit and in 2001, Sutherland's role on the program earned him recognition as Best Actor in a TV Drama at the Golden Globe Awards. The innovative series would continue to collect awards and nominations as it was renewed for successive seasons which each followed the single-day format, but took place months or sometimes years later in the timeline.As he continued to star on 24, Sutherland parlayed the show's success into some higher-profile film roles. In 2003, he played the menacing villain in the thriller Phone Booth, and the following year, he played another bad-guy opposite Ethan Hawke and Angelina Jolie in Taking Lives. 24 continued to be the actor's main gig, however, and by the time he began season six in 2006, the of character Jack Bauer had become a cultural icon as the ultimate anti-hero: and a man capable of doing or enduring anything in the name of justice, protection, or even vengeance. In addition to his work on 24, Sutherland took on a variety of voice roles (Monsters vs Aliens, Twelve, Marmaduke), and co-starred with Kristin Dunst in Lars von Trier's Melancholia (2011).
