Apparently there’s a Franco Cleef fan-made version with (original) English dub. I noticed a copy of it listed by an Amazon seller once, & hesitated about buying it because it was a little more than I wanted to pay for a pirate disc. When I checked it again a few days later it was sold, & I’ve regretted it since as I found I couldn’t get it or any other decent copy with English dub anywhere else.
If you’re determined to get an English dub & don’t care about quality, I think it’s on the Ocean Pictures DVD (Brazil), which you can probably buy a copy of from somewhere on the net.
Be warned that the picture & sound quality in Ocean Pictures DVDs is usually terrible (see thread topic,2682 - The ´how is this dvd?’ thread). I’ve had one of their DVDs before & it was almost unbearable, which is why I didn’t bother & just got the Koch edition of Johnny Hamlet instead.
