Galaxy Quest

In this sci-fi spoof, Tim Allen, Alan Rickman, and Sigourney Weaver play washed-up stars of a cheesy Star Trek-style show that ended nearly 20 years ago. Believing that the reruns they watched are real, a group of aliens head to Earth to ask for their help. The TV stars find themselves on a real-life replica of their television series spaceship, lovingly constructed by the aliens to replicate every detail from the show. Put in a real-life confrontation with a lizard-looking tyrant, the cast tries to remember lines and plots from old episodes to help them defeat him. The premise leads to hilarious lines and situations that play on both Star Trek and the actors' hang-ups. For example, Rickman's Spock/McCoy-hybrid character stares glumly at his alien gill make-up in the mirror and murmurs about the time he got five curtain calls as Richard III. Sigourney Weaver, the sexy Lt. Uhura equivalent, repeats everything the computer says. Tony Shaloub as the spaceship's Scottie-like mechanic and Sam Rockwell as the imperiled expendable officer also deliver hilarious lines.
