Delaware's movie is...

Fight Club

Although it’s not obvious at first glance, Fight Club wouldn’t really have the same impact if it had been set any place else than Delaware. Due to some very business friendly state laws, Delaware has a very low corporate income tax rate, and banks based in the state have few limits on the interest rates they can charge. That’s why many credit card companies are based in Delaware, and that’s exactly who Tyler Durden is out to bring down.
