Trivia: Peter Barton was hesitant when it came time to do his death scene, as he was previously burned by a magnesium flare doing a stunt on a previous film and required multiple surgeries afterwards. Sensing Peter's hesitation, Ted White requested that a pad be placed behind Peter's head when he was slammed into the shower wall.
Trivia: The producers purposely went with relatively unknown actors for the film, because they thought they'd be more believable than stars who people already identified in different roles.
Trivia: When Billy's mom takes the picture of Gizmo at the beginning, Gizmo becomes frightened and runs over to Mr. Peltzer. When the scene is slowed, you can see the puppeteer's hand underneath while operating the Gizmo doll. Not a mistake as needs slo-mo, but worth a look. (00:19:10)
Trivia: David Lynch was disgusted with the elongated cut of the film which includes paintings of the 'robot revolt' back story to the original film, a sub-plot he deliberately omitted. He demanded his name be removed from the credits of the film and replaced with the Director's Guild nom de plume, 'Alan Smithee'. This was done so sloppily, by superimposing Smithee's name over Lynch's, that the credit reads "A ALAN SMITHEE FILM".
