Dennis Hopper was a wonderful actor.
When he was in Gunsmoke his performances as Chester Goode virtually stole the show every time. His relationships with Doc, Matt, and Kitty were the most enjoyable aspect of that series. Even though Ken Curtis did an exc4ptional job in filling Weaver's shoes when he ledt, somehow the Chester character was less soapy than Festus. As to his performance in Duel, well it's nothing short of miraculous. Understatement and the suspension of disbelief are both handled remarkably well here and it would hard to find another that could handle this role so expertly as Dennis Weaver. I love watching the guy and I'm no cowboy.
