William Shatner (born March 22, 1931) is a Canadian actor. In a career spanning seven decades, he is best known for his portrayal of Captain James T. Kirk in the Star Trek franchise, from his 1966 debut as the captain of the starship Enterprise in the second pilot of the first Star Trek television series to his final appearance as Captain Kirk in the seventh Star Trek feature film, Star Trek Generations (1994).

Shatner began his screen acting career in Canadian films and television productions before moving into guest-starring roles in various American television shows. He appeared as Captain Kirk in all the episodes of Star Trek: The Original Series, 21 of the 22 episodes of Star Trek: The Animated Series, and the first seven Star Trek movies. He has written a series of books chronicling his experiences before, during and after his time in a Starfleet uniform. He has also co-written several novels set in the Star Trek universe and a series of science fiction novels, the TekWar sequence, that were adapted for television. Outside Star Trek, Shatner played the eponymous veteran police sergeant in T. J. Hooker (1982–1986), hosted the reality-based television series Rescue 911 (1989–1996), guest starred on the detective series Columbo, and acted in the comedy film Miss Congeniality (2000).

Shatner's television career after his last appearance as Captain Kirk embraces comedy, drama and reality shows. In seasons 4 and 5 of the NBC series 3rd Rock from the Sun, he plays the alien "Big Giant Head" to whom the main characters report. From 2004 until 2008, he starred as attorney Denny Crane in the final season of the legal show The Practice and the entire run of its spinoff, Boston Legal. The role of Denny Crane won Shatner two Emmy Awards, one for his contributions to each series.
