Revealing mistake: In the very early scene in which Zed points his revolver directly toward the viewing audience and shoots, it's visible that there is no ammunition in the gun's chambers.

Directed by: John Boorman
Starring: Sean Connery, Charlotte Rampling, John Alderton, Sara Kestelman
Other mistake: The extras in the shot where Zed pulls the cart through the courtyard of apathetic are the same extras used in the shot where he pulls into a barn. Even if they could move, that's awfully quick. These people are supposed to be zombies. (00:38:00)
