Really? Didn't know that, either.
I thought it was cool that you could definitely tell he had "the voice" going on. Even then.
It's going to be a long time before somebody else comes around with a voice like that.
My other favorite role for him was in Red October. Awesomely done.
I had read somewhere that he developed that voice because as a boy he had a problem with stuttering and he worked hard on slowing down his speech so that he could overcome it.
