Haha, well I have to point out that it's fairly rare for actors to dub themselves in these Italian films, but I do believe both MaColl and Warbeck dubbed themselves as you can hear both doing their damndest to cover up their English accents. What's strange about this movie set in Louisiana is that of all the characters in the movie, the only ones who make any attempt at the accent is Larry the painter and the giggling bookstore employee. Oh yes, Lucio Fulci may in his cameo as well. They're all possibly dubbed by the same actor.
