As i look on his Wiki article, i see now that he was scheduled to play John Rambo in First Blood. Pretty funny coincidence as i just re watched the new Rambo film. This would have been an interesting future to see. Who knows? Roy might have done it better. He sure did have the charisma.
The two roles that i see Roy Scheider as, are "Herr" Benway in Cronenberg's film Naked Lunch and Brody in Jaws and Jaws 2. He definitely brought an essence to both films. Dr. Benway was a genius creation of Burroughs and was brought to screen with the perfect cast choice. Schieder. In fact, Roy Scheider should have been in every movie ever made. I can imagine his face superimposed over E.T's face, Sean Connery's face, Hell. Scheider would have made an impressive Bond.
He's got the suave feel to him, the looks, and looks damn good smoking a pipe. That is definitely something that should have been. Roy Scheider will be remembered, if not through his badass film acting style, then definitely for one of the most remembered one-liners ever.
