Highlights from the IMDB trivia page for Face/Off:
- Originally, Nicolas Cage turned down the role of Castor Troy, citing a lack of interest in playing a villain. However, once he was told that he would actually be playing the hero for a majority of the film, he quickly signed on.
- The magnetic boots the prisoners wear in Erewhon prison are the same boots worn by the Goombahs in Super Mario Bros.
- The ornate box that is opened for Castor Troy on the tarmac contains the following: a bag of blue pills, sunglasses, 3 rolled cigarettes(or joints), a pack of Chiclets, 4 pieces of Bazooka Joe bubble gum, a switchblade, and what appears to be a blue glass vial.
- According to producer Barrie M. Osborne, most of the challenging action scenes, including the fight on the deck of the boat and the airplane going down the runway, were originally planned as green screen shots. But they filmed them practically to support the “realism of story”.
