If you think your family is screwed up, go see August: Osage County. The Weston family from Oklahoma is among the most dysfunctional you will ever witness. The main source of the trouble is the family matriarch, Violet (Meryl Streep), a pill and booze addicted woman who is filled with resentment.

Violet’s daughters Barbara (Julia Roberts), Karen (Juliette Lewis) and Ivy (Julianne Nicholson) all have their own issues, some of which have come straight from mother. Just as Violet has had a tempestuous relationship with her husband (Sam Shepard), so has Barbara with her man Bill (Ewan McGregor).

August: Osage County should win the Screen Actors Guild award for Best Ensemble. Without listing the entire family tree, here are some of the other talented actors in the film: Chris Cooper, Margo Martindale, Benedict Cumberbatch, Abigail Breslin and Durmot Mulroney.

Director John Wells and writer Tracey Letts have done an excellent job of taking a stage play to film. Only a handful of scenes have a stagey feel.

August: Osage County has been described by some as a comedy. Chris Cooper’s long-winded blessing is a classic scene and quite funny. And there are several more laughs in the movie. But, make no mistake, August: Osage County is more tragedy than comedy. The Westons are not a happy family.

Originally set for a Christmas Day 2013 release, A: OC did get the necessary runs in NYC and LA to qualify for awards season. (Expect Meryl Streep to grab an Oscar nom for Best Actress when they’re announced next week.) Don’t skip it just because it was pushed back to the movie wasteland of January. See it to witness an all-star cast delivering the goods—especially Meryl.
