Originally, Christopher Nolan had an eye on Cillian Murphy to play the Caped Crusader, with Murphy, saying in an interview with the Boston Globe.
What if, instead of Christian Bale, Cillian Murphy is offered the role and takes it. How does this change the Dark Knight Trilogy? Who plays the Scarecrow/Batman's enemy? And, most importantly, is the world ready for an Irish Batman?BG: I'm interested to talk about the rest of your year. I've read that you were excited and wanted ''Batman" for yourself at some point. You didn't get it, and did such a great job as the Scarecrow.
CM: I have to correct you. I never saw myself as Batman. It was Chris Nolan who asked me very flatteringly to come in for a screen test. I mean I don't think I have the right physique for Batman. And so I was just intrigued to get to work with Chris Nolan within a screen test situation. And then he was kind enough to offer me the other part.
