The Petrified Forest is a nice early film noir about several people's lives intertwining in a small gas station and diner in the desert. It's an early Bette Davis film, and it's also the one that started Humphrey Bogart's career.
The Dark Mirror is a relatively unknown film noir from 1946. It's about identical twins committing a murder, but which one did it? Can it ever be proven? A double dose of Olivia de Havilland in this film noir thriller directed by Robert Siodmak.
