I'm happy to see John Debney attached as the composer, not necessarily first choice, but I like his work and I'm hopeful that some of the classic music will be used, I think that's something that improved AVPR over AVP for me, the classic beating drums music and all. Silvestri created a theme for the Predators as a race, and I think it's only fitting to have those in any film about the Predators, unless Rodriguez is trying to totally walk away from the series and be unique.
I didn't realize Topher Grace would be in this too, I think this will be big for him, anything I've caught him in hasn't been a very serious role, certainly not something I'd put in a Predator movie, so be curious to see just what he brings to this movie.
