I don't know why, but when I read the story about Carradine's death I got this strange feeling that he may have killed himself because he had some sort of fatal illness and was living in pain or something. There was absolutely no indication of this in any of the stories that I've read or heard, but for some reason I just feel that this could really be the reason that he committed suicide.
I used to love Kung Fu.
I really liked his father, John, as a horror movie actor. John played a pretty damn good Dracula.
