Nightmare Alley (1947). Remade in 2021 but I’m talking about the 1947 original. Tyrone Power plays Stan, a carnival huckster who, with his wife, learns the tricks of staging a fake mentalist act and they leave the carnival to perform on their own. As their reputation and skills grow, Stan decides to try one last big-time big-money hustle, which fails spectacularly. A good old-fashioned entertaining film noir.
