I think 12 Angry Men could make quite a cool experimental game. Nothing but massive conversation trees to try to convince your fellow jurors of a guys innocence.
Then, to balance it out with something stupid and shooty, I think the next COD game should be COD:Expendables. COD's already a big macho hoohah of iffy realism, let's just make it official and have Arnie shout ridiculous instructions at me whilst Bruce Willis sighs and Sly Stallone rambles something incomprehensibly. That'd be cool.
Edit: Ooh, another one, Jackie Chan Game, don't care which movie, but if someone could recreate all of that flashy prop fighting in a game that'd be awesome. Plus, Jackie Chan is cool, he could even sing the soundtrack.
