This is Christian Bale's audition/screen test for Christopher Nolan's Batman! It's interesting to see what he was looking to bring to the character before he even got cast. There are a few interesting things in the video to note. The first is that he's wearing Val Kilmer's Batsuit from Batman Forever. The second is that he does the read with actress Amy Adams, who was eventually cast as Lois Lane years down the road. And the final thing is that his voice wasn't as growly as it ended up in the final cut of the film, but you can still see why he ended up landing the gig.
The video is included with the Dark Knight Trilogy: Ultimate Collector’s Edition, which will be released on Tuesday.
