Yeah I mean...they did offer him the role, but he was loyal to Nolan and his grounded no universe of shared heroes and powers.
Although, Im bummed to see that people have turned against the Nolan trilogy and him as Batman even with the understandable voice thing.
I didn't think the 3rd one was that bad and even had some underrated aspects to it. As for his voice, yeah it had some problems. Shame too because it seemed more force movie to movie and it was fine at the start (That scene when hes in the ski mask in Gordon's office was probably the best voice he could have gone for)
