Query: A very worth while motion picture experience.

This was one of the best thriller/mystery movies I have seen in an extremely long time. The writing was incredible and the story kept me interested all the way through. Also, some great, and eerily fascinating, performances from the entire cast, especially Steve Martin, who proves that he's not just some guy with an arrow through his head. A must see for people bored of the barrage of unoriginal garbage at their local video store.
