Galaxy Quest (1999)

A spoof of a cancelled space series could have survived as a bag of borrowed references. Instead, the actors' bruised egos gradually become the raw material of a functioning crew. Alan Rickman's resistance to his own catchphrase is funny because the character has somewhere to go. The fans' knowledge also becomes useful rather than merely embarrassing. That affection makes the comedy welcoming even if you have never argued about a starship, with the ensemble doing more lasting work than recognition alone.
