Not only is Morrell the screenwriter, he also wrote the original book that this film is based on. He discribes here what it's like to have your book made into a movie. He explains what its like to give up creative control of something you worked on to someone else. All things considered a good comentary.

Pretty interesting commentary. Describes in depth the creation, meanings behind characters, themes, action, Hollywoodization, and the cultural phenomenon around Rambo, as well as many other great tidbits about Sly and the director and filmmaking in general. Very engaging and very informative.
