Question: Was Doom II (the game played in the Ultimart) ever ported to an arcade machine? I think it would be difficult to produce a real coin-op version of the game (a lot of custom hardware and programming - I don't think any arcade hardware could support Doom back then). Making a prop would be easy by sticking a PC with a TV monitor (to prevent flicker) in a cabinet mock-up, or even just run a pre-recorded tape of someone playing Doom and just have the actor mime it.
Question: Does anyone know what kind of pistols Martin Blank uses in this film? Also, is the gunfire sound they make accurate? It's very distinctive.
Chosen answer: His pistols are 9mm Glock 17's (http://www.glock.com/g17.jpg). No movie firearm shot is authentic as it would sound very flat and unexciting because the blank rounds used are very quiet (not much louder than clapping your hands actually). The shot sounds are added in post production.
Answer: No, Doom II was never available in a commerical arcade cabinet. It must have been specifically designed for the movie.
