Brilliant and utterly unique film that is unlike any you have ever seen but still tells a very relatable story. The cast is uniformly excellent across the board, with both Cusak and Diaz unrecognizable in their roles, while Catherine Keener is a perfect femme fatale (her line, "If you ever got me, you wouldn't know what to do with me" is delivered with razor-sharp precision). Of course, Malkovich himself is perfectly game, mocking himself with glee (there is a great running gag about how everyone knows he's an actor but can't name a movie he was in). Behind the camera, director Spike Jonze and writer Charlie Kaufman craft a truly unique movie, with crazy rules that are so out there they kind of make sense (the fact Craig is a puppeteer does come into effect later). Despite the initial craziness, the film does make nice commentary on celebrity worship and wishing to be someone other than yourself, even to your detriment. Simply put, a true classic and a film that remains unique anything else made before or since.
