Bad accents - the list goes on for ever.The much shorter list is maybe that of actors who've managed good accents from far away places. Renee Zelweger in Bridget Jones is one, so was Gwynneth Paltrow in Emma.

To drift the thread a bit - any number of films seem to suggest that all young women in California quack. (The same way that men from England always seem to bark.) Is that really true?
