I thought Anakin's accent was a hybrid of American and British. British whenever he was being dramatic and American whenever he was in an action sequence.
I thought that Neimoidian pilot in ep. 3, navigating that ship Gen. Gr. was in at the start of the movie, had a New Jersey/New York accent when he said "Fire. Fire!" and "3 Jedi are in the hanger bay.." when Gen. G. asked him " Waat''s da situation, Captiin?". So?
What's the problem...?
