Why would they make Anne Australian?
Her nationality isn't even mentioned, so why would they let Abbie Cornish use her natural accent? What purpose does it serve? It seems like an incredibly random choice.
Abbie Cornish has used an American accent in most of her roles, so of all the ones to use her natural accent, why would she use it in the one where it makes the least sense? Why would an Australian go to a small Ozarks Missouri town?
I assume she stayed there because she met Bill and fell in love with him, but why would she have gone there in the first place, before she met Bill?
