People have to follow their hearts, and if their hearts lead them to Wal-Mart, so be it.
Real-life people are often the hardest to play, people that you recreate who have actually lived, because you have to live up to people's knowledge of those characters.
I quite like post-apocalyptic films, things like 'Mad Max' for instance, because they are so full on and there is something quite cleansing about the post-apocalyptic because you can see where we all think we're heading.
