I don't think it's worth getting if you already own the Anchor Bay/Blue Underground spaghetti western releases.
whys that?
Because more than 85% of the interviews shown on the Doc are all from the BU and AB releases (making the whole production feel half assed).
The only thing this doc has to offer is about 7 seconds of footage depicting LVC messin' around with Giuliano Gemma on the set of DAY OF ANGER.
It's a good view if you're new to the genre but nothing more.
At least that's how I feel about it.
Yeah, its well done doc if you haven't seen those interviews from the BU AB releases, theres a couple minutes of new interviews with Damiano, Baldi, Castellari, Howard Hughes, Christopher Frayling and Alex Cox, Robert Forster does the narration. Might be worth getting for those actually, I don't know, if you can get it cheap.
