America's Sweethearts

In this satirical comedy about the movie biz, two estranged Hollywood megastars (played by John Cusack and Catherine Zeta-Jones) are forced into a reunion for the purpose of promoting their new movie. However, the diva's sister and PA (played by Julia Roberts) is secretly in love with Cusack, and romantic comedy ensues.
Billy Crystal, who produces, writes and acts, settles a little score with Hollywood showbiz, but is wary of turning the whole thing into a pamphlet. Disguising the whole thing as a 'delightful comedy' shows that Hollywood doesn't need cold-blooded producers: self-censorship is apparently alive and well in Tinsel Town.
That said, Roberts acts uncommonly well and everybody seems to be enjoying themselves tremendously. It's a bit of an insider movie, perhaps less interesting if the freak community in Southern California doesn't concern you much, but still, there are good jokes and the pace is high. Lukewarmly recommended.
