Final answer:
Galaxy Quest is a parody of the Star Trek series, providing a comedic take on the sci-fi genre and its associated fandom by placing fictional actors in a real space adventure.
Step-by-step explanation:
The 1999 movie Galaxy Quest is a parody of the classic science fiction television series Star Trek. The film mimics the show's concept of a spacefaring crew on a mission of exploration, and it humorously reflects on the fandom associated with science fiction franchises.
Galaxy Quest showcases the adventures of a group of actors from a fictional television show who become involved in a real interstellar conflict, drawing comedy from their unfamiliarity with actual space travel compared to their scripted experiences.
