Stepping into Christian Bale’s boots is no easy feat so Batman v Superman producer Charles Roven has explained their reasons for choosing Ben Affleck.

We wanted a guy who had a certain age and a certain gravitas to what he had done in terms of his recent work.

If you take a look at The Town and Argo, he plays a couple of serious guys in those movies. He’s a big man. He’s also a mature man.

As you see him and Henry together, one definitely has much more experience just by looking at him. That’s what we wanted, particularly juxtaposed against our Superman.
