A rather simplistic, Sunday School vision of the evil of avarice and the effects of gold on the soul, where for once the great Bogey seems merely to be the vehicle for the morality play. It is made watchable by Huston and the underrated Tim Holt.
Alongside Welles' Citizen Kane & Magnificent Ambersons, I would nominate Treasure of the Sierra Madre as the greatest film of the '40s. Bogart at his best, Huston's finest film, and one of the best American movies ever made.
All writer-directors working today owe a debt to people like Huston, who helped prove to studios that writers could be trusted to be at the helm of their scripts. This is possibly Huston's best, as he pulls out all-time great performances from both his father and Bogart. Masterpiece.
