Julianne Moore, Annette Bening and Mark Ruffalo deliver some of the year’s finest performances in director Lisa Cholodenko’s funny, emotional tornado of a movie. Moore and Bening play Jules and Nic, a lesbian couple with two children (Mia Wasikowska and Josh Hutcherson) conceived through artificial insemination. The kids choose to meet their biological father (Ruffalo, who has never been so good), and all sorts of complications—both funny and heart-wrenching—ensue. This is a great movie about the challenge of keeping a marriage afloat as the years pile on, and the kids get older. Bening and Moore are so good that it hurts; they have major chemistry. Ruffalo gets high marks for his portrayal of a super-charming bastard of a man.
