I think the last “traditional” western that Clint Eastwood starred in was the television show Rawhide. Even his own The Outlaw Josey Wales, while as close as he has come to what people normally think of as a western, had enough of Eastwood’s character-based humor to make it stand apart from the crowd.
Unforgiven is not going to change that, either. Eastwood’s first Best Picture winner is less of a western than a clear-eyed rumination on the subject of violence. Some have labeled the film “anti-violence” but even that is an over-simplification that denies the film’s depth.
