Behind the scenes
"There’s another Arkham scene that involves the unseen prisoner that you see near the end of the movie, and Batman goes to him in order to profile the Riddler, because he’s being written to. So that’s a scene that I’m really excited about, and there’s a really cool seen with Colin (Farrell), with Penguin, where you see Selina (Kyle) goad him, and you get a little glimpse into a little more of his character. So those are scenes that I think we’ll probably release in some way as deleted scenes, but they’re not a part of some cut. This is the cut I wanted to make, and the one that’s in theaters is the one that I intended, and I’m really grateful that Warner Bros. let me do that. [...] Well, you know, the unseen prisoner is one of the characters that he would’ve confronted in Year 1, and that’s how he ended up there. So they have a relationship. One of the lines from the scene that’s not in is, that unseen prisoner says to him ‘It’s almost our anniversary, isn’t it?’ And you realize that they have a relationship that exists before that character, who is the character that you think he is, before that character becomes that character. He hasn’t yet declared himself that character, but they have a relationship that begins very, very early, and…they’re sort of intertwined with each other in a very specific way."
