Quoted from guyincognito:
Would a new playfield design be required to remove the drawings of the main (human) characters?
How does licensing differ if it's a drawing of a character versus a photographic image?
My personal guess is that if Skit-B is talking to Fox about a new license, a real license, some kind of license, that the playfield art isn't gonna fly.
Whatever really happened in the past with or without some special license, I don't think those actor images at the very least are approved. And it can make a big difference if it's photo vs drawing, simply in what's allowed. Meaning, they might have likeness rights at Fox to certain PR shots of Arnie, and they're only allowed to use those specific ones. No frame grabs from the film, no drawings, just that image. Anything more could mean specific actor approvals, more money, etc.
Not uncommon at all. Dutch Pinball dealt with that for TBL.
So it could be that they can make a Predator game, with the playfield and toys as it, but have to redo the art, entirely or somewhat. I'd say start over personally, if you gotta change it to use say, real photos, then make the whole thing match that style.
Lots of assumptions here of course.
