Galaxy Quest

Sci-fi spoof in which Tim Allen, Sigourney Weaver and Alan Rickman star as actors from a 1970s sci-fi TV series 'Galaxy Quest', which was cancelled after four years of broadcasting.

Twenty years on, the show is repeated on television and aliens, under attack, mistake the transmissions for historical documents and beam up the aging actors in order to save the universe.

But the cast have no script or director to help them.
