An odd one this. The plot meanders all over the place and never really finds any cohesion. The music, as Bad Lieutenant points out, is more like a Blaxploitation score. And I couldn't really say I would recommend it and yet I found it strangely compelling in a low budget, trippy kind of way.
As to whether or not it can actually be classified as a spaghetti western? I'm not sure. Weisser has it listed as a Mexican / Italian co production, but we all know how problematic that information can be. The only mention of Italy I can find on the credits is the actress, Venetia Vianelloa and a listing of personel as part of the "Sound Crew: Rome".
Does anyone have any more concrete info on this film's origins?
