Star Trek is a 2009 American science fiction adventure film directed by J. J. Abrams, written by Roberto Orci and Alex Kurtzman and distributed by Paramount Pictures. It is the 11th film of the Star Trek film franchise and is also a reboot that features the main characters of the original Star Trek television series, portrayed by a new cast and the first in the reboot series. The film follows James T. Kirk (Chris Pine) and Spock (Zachary Quinto) aboard the USS Enterprise as they combat Nero (Eric Bana), a Romulan from their future who threatens the United Federation of Planets. The story takes place in an alternate reality because of time travel by both Nero and the original Spock (Leonard Nimoy). The alternate timeline was created in an attempt to free the film and the franchise from established continuity constraints while simultaneously preserving original story elements.
