Trivia: Slither

  • Hey, It's That Guy!: Besides Nathan Fillion as police chief Bill Pardy, we have Elizabeth Banks, Michael Rooker, Jenna Fischer and more...
  • Hey, It's That Voice!: Rob Zombie as the town doctor, spoken to over the phone but never seen in person.
  • Word of God: It's not made 100% clear in the film, but according to director James Gunn on the DVD commentary, the real Grant died when he was attacked by the alien. Everything after that was the alien, although it had absorbed Grant's memories and his love for Starla. The scene with him crying early on was to indicate the alien experiencing human emotions for the first time.
