In really interesting news first reported by ComingSoon.net , Cillian Murphy auditioned for the role of Batman. Yesterday we showed a screen test similar to this of Christian Bale auditioning in the Val Kilmer bat-suit, which you can find here. The whole screen test will be included on The Dark Knight Trilogy: Ultimate Collector's Edition if you are looking to pick that up.
It makes my head spin to even consider the possibility that Murphy was up for Batman! Of course, this could have been the screen test every actor did, but imagine the difference in the film had he been the bat, with Bale taking the role of Scarecrow? Bale as Scarecrow would have been a performance that would rank up there with Heath Ledger's Joker in my opinion. I really can't wait to see this video.
