A short movie starring Penn & Teller? How sweet. A simple magic trick saves the world, it might just be plausible.

The Pitchman

Mark Mason - Pitchman

This is a great short film spanning a life of using showmanship to pitch con games, towels, and
eventually magic tricks to magicians. He tells of working on carnival rides in Blackpool and numbers games. Very interesting and worth a watch.

"Mark Mason is "The Pitchman", magic's best salesman. He started out working as a carney, running mock auctions and pitching merchandise around the UK. Now he develops and markets effects for amateur and professional magicians, often hosting the most successful and entertaining booths at the world's biggest magic conventions."
