* LesYay: The hints of some sort of romantic attachment between Laura and Donna are more explicit in the movie than the show. The fact that Laura was only seen alive in one shaky home-video-style scene in the show kept things pretty ambiguous, but the film shows a RomanticTwoGirlFriendship that ''might'' have gone somewhere else if Laura wasn't so afraid that her sexuality in general would corrupt Donna.
* OneSceneWonder: Loads of these. DavidBowie shows up for all of a minute as Agent Jeffries (whose role in the shooting script was slightly larger), Harry Dean Stanton as a bizarre trailer park landlord, etc.
