What Just Happened? was a fairly big deal at this year's Sundance mostly because of Robert De Niro who is at the center of this strange comedy. It's a Hollywood satire that some people will probably appreciate more than others, and the reviews I've read of the film have said there may be too many "insider" jokes about "the industry" for most people, but that otherwise it's a great movie.
The story follows "two weeks in the life of a fading Hollywood producer (De Niro) who's having a rough time trying to get his new picture made." Sean Penn plays himself, as does Bruce Willis (pretty hilariously, it seems) and Twilight's Bella, Kristen Stewart, also stars in the film, which opens October 3.
