Scheider is apparently very ill these days. He has Lukemia. Hope he recovers. Duel was a gimmick done as well as it could be. It's virtuso stuff from a 24 year old.
I heard that about RS. That's too bad, he was a good actor that never got his due. I've seen everything he was in with the exception of Sorcerer, which was an apparent re-make of Wages of Fear.
Wasn't Duel a "Movie of the Week?" Be interesting to see how many people came out of that...now all the directors come out of commercials and music videos.
