I am aware that there are different types of British accents (e.g. Cockney, Posh, Mancunian, etc, etc). But, I've never heard enough to be able to tell the difference between all the different types. And, like most Americans, couldn't identify what the accent was if I heard it. I assume the actors in the Harry Potter movies have pretty diverse accents given the shear number of British actors in the movie (at least it sounds like they are diverse). Can someone tell me what type of accents the various actors have?
