Followup story says that according to the police report there was no indication of assault. A maid found him. He used the curtain cords. You just never know what's going on in someone's life, but to do this a person must be in a great deal of pain. I'm sorry, for him and for his loved ones.
I agree that the focus solely on "Kill Bill" and "Kung-Fu" is unfortunate. Not a mention yet of his portrayal of Woody Guthrie in "Bound for Glory" or his Ingmar Bergman film "The Serpent's Egg." I remember his appearance on the "Tonight" show with Carson after he was overlooked for an Oscar nomination for "Bound for Glory." When Carson asked him how he felt about it, he offered a refreshing outlook: maybe it wasn't as good as I thought, he said.
According to IMDB, he has eight unreleased films in the can.
