Woody Harrelson plays a stage hypnotist/mentalist - his opening scene is hypnotizing a very mom-next-door-looking woman and then making her husband give him money to make her forget that he made the husband admit something really embarrassing. :) He also does various other things, including hypnotizing a dozen people during one of the shows. The hypnosis scenes were fun (although the power of hypnosis was somewhat exaggerated.) The magic scenes were spectacular. And the plot will keep you guessing until the second-to-last scene. (They could have left off the last scene, for all of me.)
Well worth seeing - or even just listening to, the score is fantastic.
