This reminds me of Crispen Glover years ago when he went on Letterman looped out of his mind. I think he just has major problems. I would not set aside the possibility that he has really just lost his mind on Drugs, either for the long term, or just short term "Trip". We saw what happened to his brother River when he fell into drugs. I think it is really sad, I admire him as one of the betters actors in the biz right now, and he still has so much time in front of him... It sucks to see him seem to be so at the end of the rope.

Nobody could have played Johnny Cash better than he did.
