The Spaghetti West

If you've never watched a "spaghetti" western it will give you a broad introduction. But it never really delves into the film making as a whole, and when Sergio Leone is the prime moving force in this sub-genre, some time has to be spent on how great an artist he was.

Not an extremely well-made documentary, but a great "cover-to-cover" history of the rise and fall of this genre.
