Sam Elliot. That rough ranger of a guy has such a cool tough voice that I'm sure would work. Peter Dinklage has a unique commentary voice for sure and Nolan North has a very unique voice to show emotions which is why i love him as the voice of Deadpool in animations. I don't think it works out well due to him being a -blam!-ing ghost lol being all "I'm a ghost and I'll guide your way." For any Deadpool fans I half expect him to lead me into constant danger.
