He's in a lot of movies about suicide

I guess he personally chose them. "Dead Poets Society" being one of them.

Well, he's finding out that the depiction of hell in "What Dreams May Come" is a picnic compared to the real one.

Like what?

Probably a coincidence but you never know. What killed him was his response to a brain disease called lewy body dementia. He was probably living with it for a long time. Perhaps there were signs of it going back to the 80s where he would have brief thoughts of suicide and then move on but then later on it got to be too much to handle.

Either way I don't think its fair to pin his death on a mere suicide. His brain was battling something none of us will ever get to experience.

Saddest one now is watching The Fisher King when he as Perry is at his happiest and the Red Knight comes for him, in the context of the demons that got to him with his Lewy Body Dementia in that last part of his life it becomes an even more so unsettling scene.
