An interesting tidbit for me, (& excuse me if I've mentioned this before), is that one of the more serious films he considered doing after "Two Lane Blacktop" was "Straight Time", with Dustin Hoffman. I'm sure Jon's book mentions that Karen & I had completely different versions about him starring in "Midnight Express", but I remember after he turned down "Straight Time" I saw the role played by Harry Dean Stanton, and it was quite a few years before I saw Harry in
anything that I couldn't picture Dennis playing instead...
