Galaxy Quest is a 1999 American comic science fiction film directed by Dean Parisot and written by David Howard and Robert Gordon. A parody of science fiction films and series, particularly Star Trek and its fandom, the film stars Tim Allen, Sigourney Weaver, Alan Rickman, Tony Shalhoub, Sam Rockwell, and Daryl Mitchell as the cast of a defunct cult television series called Galaxy Quest, in which the crew of a spaceship embarked on intergalactic adventures, who are suddenly visited by actual aliens who believe the series to be an accurate documentary, and become involved in a very real intergalactic conflict.
The film was a modest box office success and was positively received by critics: it won the Hugo Award for Best Dramatic Presentation (an award previously won by the original Star Trek series in the 1960s) and the Nebula Award for Best Script, and was also nominated for ten Saturn Awards, including Best Science Fiction Film, Best Director for Parisot, Best Actress for Weaver, and Best Supporting Actor for Rickman, with Allen winning Best Actor.
Galaxy Quest went on to achieve cult status through the years, particularly from Star Trek fans for its affectionate parody, but also to more mainstream audiences as a comedy film of its own. Several former cast and crew members of Star Trek also went on to praise the film. It was included in Reader's Digest's list of The Top 100+ Funniest Movies of All Time in 2012, while Star Trek fans voted it the seventh best Star Trek film of all time in 2013.
