This is a still from the opening credit sequence of Pat Garrett and Billy the Kid. It suggests something of Billy's expansiveness in placing him in the foreground of one of the many landscapes we see in the film. Some of the dialogue in the opening sequence unites Billy to these open spaces as well, and introduces Garrett as a symbol for what destroys them both.

Take a close look at the opening of this film. What are some of the ways you see these themes expressed? Why do you think Peckinpah chose to frame the film with Garrett's death, and how does he work that footage in (at the beginning and at the end) with the rest of the action?
