Directed by: David Zucker, Jim Abrahams
Starring: Val Kilmer, Peter Cushing, Jeremy Kemp, Lucy Gutteridge

Continuity mistake: Chocolate Mousse and Deja Vu are playing darts on the plane at the end of the movie. In the next shot where Hillary is hugging her father, the darts change positions. (01:23:35)
Hillary Flammond: I know a little German. He's sitting over there.
Trivia: Val Kilmer sang all of his own parts in this film. That fact was a contributing factor to his being offered the role of Jim Morrison in "The Doors."

Chosen answer: The actors were weighted down with lead plates. Oxygen tanks were kept just out of picture, and the actors used them to breathe between takes. The takes were short enough to allow the actors to hold their breath through them. The short takes were then cut together to appear as one long fight. Sound effects were added post-production.
