Re: Would Richard Grayson be part of this movie?
All those certainly fall within an acceptable age for Affleck's Batman, and are all serviceable actors.
As an aside, would people prefer Damian not exist (considering he's now dead, but may return)? And would people prefer Dick Grayson pre-Forever Evil or post (seems like he may be getting a new identity)?
