Yeah, there's a few Spanish language docs on Monzon..out there in You Tubeland and other places. None however that are really intensive..you come away not really knowing Monzon that much at all..and maybe that's not the fault of the documentary, but that Monzon was maybe unknowable. He didn't really open up and reveal anything to people..he did throw oranges at them though..lol.
Sure he may have been a killer and a woman beater, but any man who fights scurvy at the grass roots level as Monzon did has earned my respect.
