Lavinia is an all-beige-all-the-time mom, who is as filthy rich as Suzette is dirt poor. Now complete opposites, Lavinia wants to bury her past while Suzette doesn't want it to ever end. (Once famous backstage at rock concerts, they got their nicknames, the Banger sisters, from their infamous promiscuity.)

Although the movie has some funny incidents, it never seems genuine. Writer and director Bob Dolman has assembled a killer cast but is never able to get them out of first gear. One part of the casting that doesn't work is Erika Christensen (SWIMFAN), who plays Hannah, Lavinia's older daughter. Supposedly her high school's valedictorian, Hannah isn't the least bit convincing as a brainiac. Her younger sister, Ginger (Eva Amurri, Susan Sarandon's real-life daughter), is quite believable as a spoiled rich kid. The most promising part of the picture turns out to be its few bittersweet moments, but the director keeps the focus firmly on the comedy. It's a movie that delivers a few good laughs and that's about it.

THE BANGER SISTERS runs 1:37. It is rated R for "language, sexual content and some drug use" and would be acceptable for most teenagers.
