Sadly, I haven't. *cough*
Also, this is amazing.
By Jove! That is the worst fate anyone could ever experience...
Well...
If you watch the Batmans with Michael Keaton in them, he makes his voice somewhat more gravely to disguise who he is. I can't remember if Val Kilmer did that but I know George Clooney didn't but he was probably the worst Batman anyway so no one really cares. They didn't do it in the cartoon because...it was a cartoon. Bale's voice isn't bad, per se, but I think he takes it way too far. It sounds like he's trying to gargle cement.
