This conversation is going to be more productive (and more enjoyable, quite frankly) if we consider actors according to their broader talent and aesthetic. OJC fits the appropriate age range, he has a proper Bruce Wayne look, and he's a talented guy. Makes perfect sense that he'd be a candidate worth discussing, especially this early in the process when they haven't even begun the search yet. We can get into the weeds with this sort of analysis when we actually have a tangible shortlist of actors to work with.
