William Shatner 

William Shatner is best known for his role as Captain James T. Kirk on the Star Trek series and films. He now writes all those TekWar books and has some cameo appearances in various films.

William was born on March 22, 1931, in Montreal, Quebec, Canada. He studied business at McGill University for a while and intended to join his family's garment firm but soon decided to follow his passion: acting.
Shatner made his feature film debut as 

one of The Brothers Karamazov in a 1958 film version starring Yul Brynner.
After turning in his first big-screen lead performance in the drama The Explosive Generation (1961), Shatner moved to New York City and began working on projects in television.
He starred as an assistant district attorney in the short-lived drama series For the People (1965) before landing the role that would make him famous: the self-assured Captain James Tiberius Kirk on the science fiction TV series Star Trek (1966-69).
Several of his novels were made into television movies and a series, in which Shatner starred and which he also directed.
In the late 1990s, the tireless Shatner made news again for his quirky appearances in a series of high-profile television commercials for the Internet company Priceline.com.
His most recent feature film role was a supporting turn as a beauty pageant official in the comedy Miss Congeniality (2000), costarring Sandra Bullock, Benjamin Bratt, Michael Caine, and Candice Bergen.Shatner has three daughters, Leslie, Lisabeth, and Melanie, from his first marriage, to Gloria Rand; a 20-year union to the actress Marcy Lafferty ended in 1996. Shatner married his fourth wife, horse trainer Elizabeth Martin, on February 13, 2001.
