Galaxy Quest is a 1999 science fiction comedy that cleverly parodies the tropes of classic space operas, particularly the Star Trek franchise. The film follows the cast of a canceled television series, “Galaxy Quest,” who are inadvertently drawn into a real interstellar conflict when a group of genuine aliens, believing the show’s episodes to be documentary footage, seek their help to save their civilization from a tyrannical warlord. The ensemble cast, led by Tim Allen as Jason Nesmith (the show’s captain), includes Sigourney Weaver, Alan Rickman, and Tony Shalhoub, each bringing humor and heart to their roles.
