This movie, written and directed by Chris Rock, made a huge splash in Toronto this year, ignited a bidding war over distribution, and is now being quickly slated for a release on December 5th, in time for awards consideration. It got some very enthusiastic reviews, although I don't know if you can tell what makes it so special from this trailer- it looks funny, but apparently it's more than that, with some serious points to make about a variety of topics, including Hollywood, relationships, etc. Some referred to it as Chris Rock's Annie Hall, if that gives you a better idea of what it might be. Looking forward to seeing it though- I hope it can live up to the hype.
