Although the 12 film posters displayed above (click on them for a larger version) may seem random, they follow a certain pattern. One of them, however, doesn't belong here.
Can you find the pattern? And which film (poster) doesn't belong here?
Note: There is an actual pattern to the film posters, so the order matters. It's not about whether one film poster doesn't show something while the others do (or vice versa), or whether a film has a different theme than the others.
