Being Julia (2004)

Synopsis
A woman scorned unleashes her fury in this droll comedy based on a story by W. Somerset Maugham. Julia Lambert (Annette Bening) is a famous and well-respected actress, but though her life in the limelight seems glamorous, things are not going well for her off-stage. Julia's husband is unfaithful to her (and not especially discreet about it), her son is angry with her, and she's afraid she's losing her looks and allure as she advances further into middle age. In the midst of this, Julia meets a handsome and dashing young American named Tom.. Tom makes no secret of his attraction to Julia, and the feeling is mutual, leading the two into a torrid affair. But, while Julia at first dives into this adulterous romance with little care for how it could affect her reputation, she becomes livid with rage when she learns that Tom is also involved with a younger actress, and is only using Julia to advance himself. Julia then plots an elaborate revenge against Tom in a scheme that will help her win back the pride and confidence life has recently stripped from her. Being Julia also stars Jeremy Irons, Michael Gambon, Bruce Greenwood, and Shaun Evans. ~ Mark Deming, All Movie Guide
