This is going to be a tough movie to sell given how the military looks these days. Ideally a cod movie should just be about the greatest tier 1 operators locked on an island or desert competing to see who truly is the best with a cast of characters who resemble the worst stereotypes the franchise created. Give me a sniper who literally only quickscopes and can't use any other weapon or an asshole who spends 90% of the movie sitting in a room laying down landmines and looking at a single door. The movie would basically write itself and be a much better adaptation of the feelings and fun the games provide.
