Just a month or so I ago I rewatched "Treasure Of The Sierra Madre". An incredible movie well deserving of it's accolades.
I have often said that it's rare for an actor to carry a role throughout a film and maintain excellent performance. I often note as one of the 'few' who did so being George C. Scott in Patton. But in "Treasure Of The Sierra Madre".. AS IN "Casablanca"...something even more rare occurs - - - EVERY actor involved does exactly that.... simply aces their performance throughout, in ever single scene.
