The Movies, man! The Movies!

If you haven't heard anything about it, it's like a sim where you are in control of a movie studio, with a good mix of The Sims thrown in (for instance, you can create stars from scratch and manage their daily lives as well). The part of the game that has me the most excited is the fact that you can make full movies using the game, dub it over with your own voice and effects if you want, then upload it to the web for others to view.
