"The Ninth Configuration" with director's commentary.

I can't interrupt that film even to listen to Bill Blatty (something I never tire of even when he is talking utter nonsense, God I hope I can spend some portion of an afterlife chatting to his spirit, even if it's a long distance phone call from heaven, where he will be, to hell where I am frequently informed I shall be).

I had to switch the picture off for the commentary and just listen because everytime I see those faces I just want to listen to what the guys are saying.

The dialogue is like the tunes on a favourite album.

As insightful as the composer's thoughts might be you don't want him talking over the actual tunes.
