I think Ledger nailed that accent - from the minute I saw the trailer, I KNEW he'd gotten it perfect - the American tone, the Western tone, and the suppressed man for whom expression is real effort. It was brilliant work, and I never thought he was mumbling. He was terse, he was soft-spoken, but I understood every word, every grunt that wasn't a word, every whispered "it's all right" from Jack and every sound that Ennis made.
And Stephan, I'm with you on that 'voice I'd wanna hear in my ear' - my S.O. has a low voice too, and it sends vibrations right down to my, well, you know.
Even when I read the book, I heard a similar voice - most clearly when Ennis replied to Jack's first postcard. Those two words, "YOU BET". God, how hot is that? I hear them as a very masculine, very aroused grunt " y o u b e t " with all the 'jouncing the mattress' that that implies. :fans self:
