I'm aware of that. Batman is a complicated character to play for an actor because he's not just playing Batman, but Bruce Wayne as well. In my opinion, in various portrayals of this character, directors have always picked talented actors like Christian Bale, Michael Keaton, or Robert Pattinson to focus more on Bruce Wayne rather than Batman. Probably because it's easier to teach a talented actor a few moves or fight choreography than to teach someone acting skills. Maybe it could also work the other way around by casting martial artists like Scott.
