Australia - The Movie preview

Ok, I really want to see this, not only because I am Australian, but I mean, come ON. HOW THE HELL DOES NICOLE KIDMAN HAVE AN ENGLISH ACCENT????

She is not ENGLISH, she is supposed to be Australian, in real life AND in the film. URGH! She annoys me to no end, and if she ruins this movie just because she is a loser trying to put on a posh accent I will hunt her down...
