I've only lived in Bristol for 25 years, but I must say I get a bit annoyed on the city's behalf when George Lucas describes David Prowse's accent as "hilarious" (to say nothing of "Scottish"). Why shouldn't Darth have a Bristol accent, as much as any other?
What's even more annoying is that even when he was Green Cross Man Prowse was still overdubbed by an actor with something closer to Received Pronunciation.
Just to note - if ever I get to cast Alexander the Great he will have an Inverness accent, as is proper. Alfred the Great will be pure Somerset.
