Galaxy Quest

"Once upon a time, a troupe of has-been actors that starred on an old sci-fi show were enlisted by an alien race to save them from an intergalactic tyrant. Despite being way out of their depth, the cast somehow managed to save the aliens and stay alive ... but their actions in outer space may have had dire consequences for another world. The cast of Galaxy Quest have enjoyed a career resurgence since returning from their intergalactic adventure, but all that is about to be interrupted by Qint, an alien with a very surprising ax to grind against Jason Nesmith and the crew of the NSEA Protector!"--
