If James Brolin was maybe, a decade younger, could he have made a good Bruce Wayne?
Looking at these photo of him, it just occurred to me how much he as a young man looks like Christian Bale:

Of course, Brolin appeared in Tim Burton's Pee-Wee's Big Adventure as the movie within a movie Pee-Wee Herman (with Morgan Fairchild as his leading lady).
