I seriously doubt it too, unless he dubbed other actors in films he wasn't even in as well.
Volonte did NOT dub his own voice. It was Paul Frees.
Yeah, dude, haven't you been listening?
But it was Paul Frees.Compare Ramone's voice, the captain's voice, and Morton's voice to El Indio.They're all the same.
I want to add some news about Carlo Giuffrè (who was playing the Union captain). He recently reminished about GBU and revealed that when playing opposite Eastwood couldn't understand a single word of what he was saying, of course, as he doesn't speak English. Also, it is (for Italians) slightly paradoxical that Giuffrè, a Neapolitan by birth and raising, i.e. a southern man, was playing a "northern" captain.
Peace, I was just reiterating what you had been saying.
That's why he was great in the role of a drunkman,having that stupid expression on his face all the time.
