More trivia for Batman Forever
Question: At the beginning, when Batman breaks through the helicopter's window with his head, he tells Two-Face, 'Give it up, Harvey. You need help' or something like that. But this voice is totally not what Val Kilmer sounds like. The best I can come up with is that it's a stunt double or something like that. If anybody out there knows the real reason, I'd be happy to hear it.
Answer: I have noticed that as well. It doesn't seem like his voice is wrong, it just sounds like he says "give it up" twice at once or something. Maybe an issue in post-production.
Chosen answer: Batman talks like that because if he talks like Bruce Wayne (Val Kilmer's voice) his voice might be recognized, leading to Batman's identity being revealed.
