I haven’t seen The Dark Knight yet but watched Batman Returns over the weekend. I noticed the cheesy gravelly voice that Christian Bale used also - didn’t know if it was to disguise his voice, or that he was really angry that he had to wear that heavy batsuit.
Probably because he had to pee real bad and Morgan Freeman didn’t put in a porta-potty in the suit.
Do you perhaps mean Batman Begins?
Regards,
It’s to disguise his voice. I remember a Batman cartoon from when I was a kid. Bruce Wayne and Batman had different voices.
