Andrea Riseborough in Talks For August: Osage County Film, Starring Meryl Streep & Julia Roberts

British actress Andrea Riseborough is in talks to star as Karen in the forthcoming film adaptation of Tracy Letts’ Tony and Pulitzer Prize-winning play August: Osage County, according to U.K.’s Daily Mail. The previously announced film will also star Academy Award winners Meryl Streep and Julia Roberts, and will be produced by George Clooney, Grant Heslov and Harvey Weinstein. The movie will be helmed by John Wells and adapted by Letts. No filming or release dates have been announced.

August: Osage County is the story of the Weston family, who reunites at their rural homestead in Oklahoma after the disappearance of Beverly, the alcoholic patriarch. Streep will play Violet, the pill-popping and deeply troubled mother of the family. Roberts will play Violet’s older daughter Barbara, while Riseborough will reportedly play Violet’s youngest daughter. August: Osage County premiered at Chicago’s Steppenwolf Theatre Company, then transferred to Broadway on December 4, 2007. The production won the 2008 Tony Award for Best Play before playing its final performance on June 28, 2009.

Riseborough has appeared off-Broadway in The Pride. Her film and TV credits include Happy-Go-Lucky, Made in Dagenham, Never Let Me Go, W.E., Brighton Rock, Mad Sad & Bad, Resistance, The Devil’s Whore and Party Animals.
