Now just a thought, not that I'm advocating doing anything wrong, but what if people happend to show up to see the film but refused to pay for whatever reason. Perhaps maybe because they don't want to support Michael Moore in a capitalistic way.
Now don't worry there is a an antidote if you happen to accidentally watch a Moore film. I recommend picking up a copy and reading Atlas Shrugged by Ayn Rand. (In my humble opinion is one of the most influential books I have ever read .)
I hope he takes a loss on this one, and I bet he blames everyone but himself for it. snicker! But if you saw it plase write a review in the comments section.
