Tawny Madison" (SIGOURNEY WEAVER) and "Dr. Lazarus" (ALAN RICKMAN) - set off on thrilling and often dangerous missions in space...and then their series was cancelled!Now, twenty years later, aliens under attack have mistaken the Galaxy Quest television transmissions for "historical documents" and beamed up the crew of has-been actors to save the universe.
