This was the last movie shot at Stapleton Airport in Denver, which was featured in movies such as Die Hard 2 and Dumb & Dumber. They stopped the jackhammers for half a day for the production crew to shoot the two airports scenes.
Trygve Lode, who plays the villain Therion, also did the vocals for the song, "Now You're Mine (sei Meine)" heard in the background in the Inferno club.
