Yes, my English teacher showed us this movie. I think it's an horrible story, I can't believe that really did happen. The movie and the book are great though, recommended for sure.
Back to the topic, I don't think anyone here wouldn't eat the body. If you're starving to death, like 10 days without eating, I think you wouldn't mind eating your friend anymore. I couldn't let myself die, 100% sure. I would eat him, even though it's fucking disgusting.
