The Oscars can’t be expected to get it right every time, but when it comes to the acting categories it’s particularly obtuse. (Joel Grey in Cabaret over Al Pacino in The Godfather? Art Carney in Harry & Tonto over Pacino in The Godfather, Part II? Pacino in Scent of a Woman over Clint Eastwood in Unforgiven? ) Often, great performances don’t even land a nomination. Here’s a list of 20 of the most unbelievable acting Oscar snubs.

1. Ingrid Bergman as Ilsa in Casablanca (1942)

It’s hard to believe, but the future winner of three Academy Awards had just started working in Hollywood and wasn’t nominated for her most immortal performance, the one that defined screen glamor.
