just a random thought...anything they use that is remotely attached to the movie has got to be approved. (i.e. the dude's image on their facebook page (500 likes)....Sam Elliot in the picture behind the models in the VIP picture, maybe even the shot of Jesus at the bowling alley on their facebook page as well)
I think that these images will be used somewhere on the game. I don't think that they would go through all of the approvals and not use those images somewhere on the game.
What I invision is artist rendering on the playfield with the BG 'photo type'...but I also think that with them having the same guy on board that did the LCD graphics on WOZ, there will be an LCD in the backbox, bringing in movie clips as certain targets/modes are achieved.
