Well, an online friend wrote me back about this book and the 5 I never heard of are no such thing. They actually listed 6 and I have 4 of those already including Seven Men From Now and The Naked Spur. They list some films others wouldn't consider westerns, like The Treasure of Sierra Madre but have the nerve to list Dances With Wolves and also say that one isn't a western. Despite these flaws, my friend says he does enjoy this book.
