Why was he in so much pain. Depression? Exhaustion for working too hard? What was goin' on with him, does anyone know yet?
From what I can gather, he was haunted and distraught over his role as the Joker in the new Bat Man movie because the Joker is so evil and hateful. Apparently he struggled with the role and it kept him up at night thinking about it. This is what I've been hearing from the media reports.
Once again this just shows us what a brilliant and dedicated actor Heath was. He was willing to take on and tackle any role, no matter how difficult.
Poor Heath!
