Years after cancellation, the stars of the television series Galaxy Quest cling to their careers. When a distressed interstellar race mistakes the show for "historical documents," lead actor Jason Nesmith (Tim Allen) and his crew of has-beens are unwittingly recruited to save the alien race from a genocidal warlord. Featuring an all-star ensemble, including Sigourney Weaver, Alan Rickman, Tony Shalhoub, Sam Rockwell, Daryl Mitchell, Justin Long and Rainn Wilson, Galaxy Quest is a hilarious adventure that boldly goes where no comedy has gone before.
