Trivia: For an actor almost universally associated with a single character -- Captain James Tiberius Kirk of the U.S.S. Enterprise -- William Shatner has found diverse ways to stay active in the public eye, even spoofing his overblown acting style in a way far more hip than desperate. Years after he last uttered "warp speed," Shatner remains a well-known face beyond Star Trek conventions, re-creating himself as the spoken-word pitchman for priceline.com, and starring in a popular series of smoky nightclub ads that featured some of the most cutting-edge musicians of the day.The Canadian native was born on March 22, 1931, in Montréal, where he grew up and attended Verdun High School. Shatner studied commerce at McGill University before getting the acting bug, which eventually prompted him to move to New York in 1956. He initially worked in such live television dramatic shows as Studio One and The United States Steel Hour in 1957 and 1958, as well as on Broadway. His big screen debut soon followed as Alexei in the 1958 version of Dostoyevsky's The Brothers Karamazov.Throughout the 1960s, Shatner worked mostly in television. His most memorable appearance came in a 1963 episode of The Twilight Zone entitled "Nightmare at 20,000 Feet," in which he plays a terrified airline passenger unable to convince the crew that there's a mysterious gremlin tearing apart the wing. He also appeared in such films as Judgment at Nuremberg (1961) and the bizarrely experimental Esperanto-language horror film Incubus (1963). In 1966, he got his big break, though neither he nor anyone else knew it at the time. Shatner was cast as the macho starship captain James Kirk on Star Trek, commanding a crew that included an acerbic doctor, a Scottish engineer, and a logician with pointy ears, on a mission "to boldly go where no man has gone before." However, the show lasted only three seasons, considered by many to be high camp. After providing a voice on the even shorter-lived animated series in 1973, Shatner must have thought Star Trek too would pass. A costly divorce and a lingering diva reputation from Star Trek left him with few prospects or allies, forcing him to take whatever work came his way. But in 1979, after a decade of B-movie labor in such films as The Kingdom of Spiders (1977) and a second failed series (Barbary Coast, 1975-1976), Shatner re-upped for another attempt to capitalize on the science fiction series with Star Trek: The Motion Picture. This time it caught on, though the first film was considered a costly disappointment. With dogged determination, the producers continued onward with Star Trek II: The Wrath of Khan (1982), at which point fans finally flocked to the series, rallying behind the film's crisp space battles and the melodramatic tête-à-tête between Shatner and Ricardo Montalban.Shatner had to wrestle with his advancing age and the deaths of several characters in Star Trek II and Star Trek III: The Search for Spock (1984), but by Star Trek IV: The Voyage Home (1986), the actor got to indulge in his more whimsical side, which has since characterized his career. As the series shifted toward comedy, Shatner led the way, even serving as director of Star Trek V: The Final Frontier (1989), which many considered among the series' weaker entries. During this period, Shatner also began parodying himself in earnest, appearing as host of Saturday Night Live in a famous sketch in which he tells a group of Trekkies to "Get a life." He also turned in a wickedly energetic mockery of a moon base captain in Airplane II: The Sequel (1982). Shatner made one final appearance with the regular Star Trek cast in Star Trek VI: The Undiscovered Country (1991), then served as one of the crossovers to the new series of films in Star Trek: Generations (1994), in which endlessly theorizing fans finally learned the fate of Captain Kirk.The success of the Trek movies reenergized Shatner's TV career, even if it didn't immediately earn him more film roles. Shatner played the title role on the successful police drama T.J. Hooker from 1982 to 1987, directing some episodes, then began hosting the medical reality series Rescue 911 in 1989. Shatner returned to the movies with another parody, Loaded Weapon I, in 1993, and in 1994 began directing, executive producing, and acting in episodes of the syndicated TV show TekWar, based on the popular series of Trek-like novels he authored. In the later '90s, Shatner was best known for his humorously out-there priceline.com ads, but also guested on a variety of TV shows, most notably as the "Big Giant Head" on the lowbrow farce Third Rock From the Sun. He also appeared as game show hosts both in film (Miss Congeniality, 2000) and real life (50th Annual Miss America Pageant, 2001). In 1999, Shatner suffered public personal tragedy when his third wife, Nerine, accidentally drowned in their swimming pool. The champion horse breeder and tennis enthusiast owns a ranch in Kentucky and remains active in environmental causes. Shatner took on a small role for 2004's Dodgeball: A True Underdog Story, and voiced the villainous wildebeest Kazar in Disney's animated adventure The Wild in 2006. Shatner returned to television for a starring role on the popular dramady Boston Legal, in which he plays Denny Crane, a once unbeatable lawyer who co-founded the successful law firm where he continues to work despite his reputation as an eccentric old man.

Trivia: Philadelphia-born James Darren came to Hollywood armed with far more impressive credentials than most teen idols, notably several years' training with Stella Adler. Signed to a Columbia Pictures contract in 1956, Darren was developed into a popular leading man-and, briefly, a recording artist. Columbia required him to show up in everything from 1958's Gidget to a 1965 episode of TV's The Flintstones (as "Jimmy Darrock"). In 1966, Darren was cast as Dr. Tony Newman on the Irwin Allen sci-fi TVer Time Tunnel, wherein he was given the unenviable task of reacting in alarm to miles and miles of 20th Century-Fox stock footage. After Time Tunnel folded in 1967, Darren's career was one of a few peaks and several valleys. Though he'd never really been away, Darren made what was labelled a comeback in 1982 in the solid supporting role of Officer Jim Corrigan on the weekly William Shatner TV vehicle T.J. Hooker. Since that time, James Darren has received a number of plum guest-star assignments on various TV dramatic and comedy programs, and has directed individual installments of such programs as Police Story.

Trivia: Though early on, short, pugnacious American actor Gerald S. O'Loughlin dreamed of becoming a lawyer, the prohibitive cost of law school forced him to steer toward engineering as a career. O'Loughlin was deflected from this ambition by an increasing interest in the theatre. After a long stint with the Marines, O'Loughlin used his GI Bill money to finance his participation at the Neighborhood Playhouse in New York. Working steadily on stage and in live TV drama, O'Loughlin made an inauspicious debut as the romantic lead in the Manhattan-filmed turkey Lovers and Lollipops (1956); one year later, he was shown to better advantage re-creating his stage role in the filmization of Michael Gazzo's play A Hatful of Rain (1957). For many children of the '70s, Gerald O'Loughlin will always be the tough-but-tender Lt. Ryker on the long-running cop series The Rookies. Even in his subsequent TV series assignments (Automan [1983-1984], Our House [1986]) one half expected O'Loughlin to drop character and start barking out "Hey! Danko." Gerald O'Loughlin was married to casting director Meryl Abeles.

Trivia: The son of a musician, African American actor Clarence Williams III was raised by his grandmother. While attending his local YMCA branch as a teenager, Williams became interested in dramatics. After a two-year hitch with the Air Force, he began his acting career, making his New York debut in 1960's The Long Dream. Williams amassed an impressive list of Broadway credits, and in 1966 was artist in residence at Brandeis University. Still, he remained an unknown commodity in Hollywood until 1968, when he was cast as "hip" undercover cop Linc Hayes on the popular TV weekly The Mod Squad. After the series' cancellation in 1973, Williams divided his time between stage and film work, occasionally functioning as a director. Among his better-known assignments of recent years was the role of Prince's father in Purple Rain (1984) and the recurring part of Roger Hardy in the cult TV series Twin Peaks (1990). Clarence Williams III is married to actress Gloria Foster.
