A ticking-time-bomb insomniac and a slippery soap salesman channel primal male aggression into a shocking new form of therapy. Their concept catches on, with underground "fight clubs" forming in every town, until an eccentric gets in the way and ignites an out-of-control spiral toward oblivion http://www.imdb.com/title/tt0137523/
Your head will collapse, and there's nothing in it. And you'll ask yourself... This is a quote from the film Fight Club. Fight club is another example of a film that blends reality and fantasy. You are never sure who is the real person or not. This again challenges the audience. I love the way that they have not made Tyler Durden a gimmick but have made him into a real character who then transforms into another.
