Demolition Man - Production

Production

General Motors provided the production team with 18 concept vehicles, including the Ultralite concept vehicle. More than 20 fiberglass replicas of the Ultralite were produced to portray civilian and SAPD patrol vehicles in the film. After filming had completed, the remaining Ultralites were returned to Michigan as part of GM's concept vehicle fleet. The movie also features a 1970 Oldsmobile 442 in its chase scene.

For some non-American releases, references to Taco Bell were changed to Pizza Hut. This includes dubbing, plus changing the logos during post-production. Taco Bell remains in the closing credits. In the Swedish release the subtitles still use Taco Bell while the sound and picture has been altered as above. The original version released in Australia (on VHS) contained Taco Bell, yet the newer version on DVD was changed both in logo and dubbing to Pizza Hut. (In the scene where the restaurant patrons are looking through the glass windows to the fight scene outside, "Taco Bell" can be seen etched into the glass, even in the modified version.)

In one scene, Phoenix makes a comment about serial killer Jeffrey Dahmer being one of the cryo-inmates. Since this movie was made before his death in prison in 1994, in this alternate time period, he had been frozen with all the other criminals that were deemed too dangerous. Later versions of the film have this comment deleted.

Hungarian science fiction writer István Nemere claims that most of Demolition Man is based on his novel Holtak harca (Fight of the Dead), published in 1986. In the novel, a terrorist and his enemy, a counter-terrorism soldier are cryogenically frozen and awakened in the 22nd century, when violence was purged from society. Nemere claimed that a committee proved that 75% of the film is identical to the book. However, Nemere chose not to initiate a lawsuit, as it would have been too expensive for him to hire a lawyer and fight against major Hollywood forces in the United States. The author claims that Hollywood had ripped-off works of many Eastern European writers after the fall of the Iron Curtain, and that he knows the person he claims to be responsible for illegally selling his idea to the filmmakers.
