Well no actor is going to devote 75% of his time to lifting & 25% of it to the skill of acting, if they do, I can assure you they won't be a good actor. Actors study the art of acting to be as good as they can be, so you're never going to find a 'roided out one who can act, including Arnold. He got catapulted into acting because he was huge, he's gotten better over the years, but not close to being an Oscar worthy actor. So if you want a 'Dark Knight' style movie for Cap, forget about getting a muscular guy. You want the movie to be good? or do you just want to look at a guy?
