A new special feature has been released for the upcoming The Dark Knight Trilogy: Ultimate Collector's Edition, and it focuses on the casting of Batman. We've already seen the screen test for Christian Bale, and now we have the video footage of Cillian Murphy and Eion Bailey auditioning for the part as well. In the process, Christopher Nolan explains why they didn't end up in the role. Both of them would have brought something completely different to Batman. I'm glad they went with Bale. He just brought a certain weight to the role that you don't see with this other two actors. But Murphy was perfect as the Scarecrow!
If you don't want to watch the whole video, Bailey's audition is at the 2:05 mark, and Murphy's starts at the 6:23 mark.
