You must must see The Whole Wide World. I just found out he produced, as well as starred in this movie. He plays the man who created the graphic novels (and character) - Conan the Barbarian. It is about him being unable to conquer his own demons, although for a brief period he is happy because he meets and falls in love with a young lady, portrayed by Rene Zellweger. I don't know if you saw it but Rene Zellweger, in her acceptance speech for her Oscar thanks Vincent D'Onofrio (apparently he was instrumental in her being cast in his movie.)
