My favourite movie quote is from Shakespeare in Love:
Philip Henslowe: Mr. Fennyman, allow me to explain about the theatre business. The natural condition is one of insurmountable obstacles on the road to imminent disaster.
Hugh Fennyman: So what do we do?
Philip Henslowe: Nothing. Strangely enough, it all turns out well.
Hugh Fennyman: How?
Philip Henslowe: I don’t know. It’s a mystery.
