For BvS? Or just the previous movie. Because in the interview, the way I interpreted it, he's pretty clearly talking about Batman vs Superman, and when he says there is "already another version of the character" I only miss the words "in the movie". I really don't see them sticking with Ryan Reynolds but I dunno. But like I said I might be looking to much into it.
He had previously said a few months ago the character he would be playing had not been seen live action before. I'm sure it was just a reference to those earlier comments. I understand that it would sound confusing without that context.
