Why So Deep-Voiced, Christian Bale?

Those of us who saw Dark Knight all had the same complaint about the movie: Christian Bale’s Batman voice was equivalent to a person leaving the dentist’s office full of novocaine who was just punched in the throat. Luckily, someone posted a Youtube video of the interrogation scene between Joker and Batman so that all people may enjoy the terribleness of Christian Bale.

NOTE: Not actually from the movie, so it’s safe to watch those of you who don’t like spoilers.
