Galaxy Quest/Trivia

Fake Nationality: Parodied with Arab-American Tony Shalhoub playing Chinese-named Fred Kwan/Sgt. Chen, a reference to Japanese-American George Takei playing totally not Japanese-named Sulu on Star Trek the Original Series, Englishman Patrick Stewart playing French Jean-Luc Picard on TNG, and Canadian James Doohan playing Scotty.
- Kwan isn't even his real name. He visibly squints for the camera in an attempt to make his eyes look Asian.
Hey, It's That Guy!: Justin Long, the Mac Guy (from the "I'm a Mac, and I'm a PC" commercials) in his first film role as one of the Galaxy Quest fanboys.
- Also Dwight Schrute (Rainn Wilson) as one of the aliens! And Ted Buckland (Sam Lloyd) as another!
  - And Crewman Daniels as a third!
- And Adrian Monk!
  - He even mentioned how clean the floor of the space ship was.
  - Though the trope applied at the time, audiences would have recognized him as the Funny Foreigner from Wings.
- Alexander is Hans Gruber!.
  - And the Sheriff of Nottingham, and the Metatron, and Severus Snape...
    - (You are reading this in Mr. Rickman's bored voice)
- Daddy Mars is Mathazar, the head alien!
