I know he had a bald patch at the back of his hair that disappeared in Batman so something was done but I'm sure when promoting Batman he had the bald patch again on the Letterman show. Keaton's hair is funny but he pulled off the look in my opinion.
Anyways this is looking awesome and I too hope that he is rigged out looking like the MIME scene from the movie. I also hope he comes with two red roses.
It's a well documented fact that there is not enough variation of Keaton-related merchandise considering how long he's been in showbiz. So bought. Will definitely do a custom Bruce Wayne next to the DX09.
