The 1960s were a great time for stylish heist movies, with many classics which are still loved by fans decades later. The heist genre initially sprung out of film noir, but it gradually developed its own identity, and it came to encompass romantic comedies, action thrillers and even spy movies. The 1960s marked a boom for the genre, after films like Rififi and The Killing brought about a new wave of enthusiasm in the 1950s.
