An American Hero's Journey: The Rambo Trilogy (2002)
This documentary combines many movie clips with remarks from First Blood novelist David Morrell and author of The Writer's Journey Christopher Vogler. The former provides some good background and anecdotes about the movie; Vogler takes more of a symbolic and interpretive view of Rambo. He traces the path followed by our hero through all three movies and connects it to mythology and other basic story-telling notions. "Journey" manages to end the documentaries in a reasonably rich and useful way.
