Well, I dunno if this helps, but I just read an article with an interview with an Id member who said they're making the movie company follow a lot of DOOM "rules" whatever those are supposed to be.

DOOM 3's lead designer Tim Willits: "We helped interoduce the game to the writer. There are some Doom rules that Universal had to follow, so we've been very happy with that. Plus, the production staff is top-notch. ... Stan Winston studios is handling effects for the Doom film, and they are the group that did Aliens and the original Star Wars, so..."

I doubt that really helps much, but it's something. At least Id will be satisfied with the film. Though that really doesn't help me, since I don't agree with Id anymore. I miss the real DOOMs. They should do a re-make and just enhance the graphics and leave everything else alone.
