Trivia: John Cusack's real-life sister, Joan Cusack, is wearing a neck brace on the bus at the beginning of the film.

Trivia: This was Johnny Depp's first movie.

Trivia: Director Ivan Reitman performed the demonic voice of Dana/Zuul in the bedroom scene with Peter Venkman.

Trivia: Most of Prince's dance moves are his own personal tribute to the "Godfather Of Soul" James Brown.

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: Just in case some people don't know, most of the "German" in this movie is total gibberish. Some sentences are perfectly correct and properly spoken, as with the welcoming speech, the German soldiers and platform announces at the station, the "Ich liebe dich, mein Schatz", etc. But the learning tape, the conversations at the Culture Hall during dinner and the East Germany Anthem are just a bunch of "German-dutch sounding noises." Of course, it's even funnier to know that there are subtitles for all these with content that has nothing to do with it.

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: 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".

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: Originally, Rob Reiner was going to be in the band, but decided on just directing the film after the comment, "he didn't look good in spandex," was made by Harry Shearer.

Trivia: Haing S. Ngor and Dith Pran actually met up in real life and even visited the old country - Vietnam - together before Haing's death.
