One thing you’ll never, ever see in an action film is a supporting player (bad or neutral guy) who stands up and is ready to fight or shoot it out with a lead guy, and then — very sensibly! — changes his mind when he realizes that beating or out-drawing the lead guy isn’t in the cards. It happened 52 years ago in Butch Cassidy and the Sundance Kid, but it hasn’t happened since.
If I’m wrong please remind me of another scene that works like this (i.e., “Uhhm, wait, hold on…I can’t win this one.”).
The card player’s name was Donnelly Rhodes, and he died three and a half years ago. He was 40 or so when he shot this scene with Robert Redford, Paul Newman and director George Roy Hill.
