Dermot Mulroney Joins Meryl Streep, Julia Roberts & More in August: Osage County Film

Dermot Mulroney is set to star as sleazy businessman Steve in the forthcoming film adaptation of Tracy Letts’ Tony and Pulitzer Prize-winning play August: Osage County, according to Deadline.com. Mulroney joins previously announced Academy Award winners Meryl Streep and Julia Roberts, as well as Tony nominee Margo Martindale, Abigail Breslin and Juliette Lewis. Adapted by Letts, directed by John Wells and produced by George Clooney and Grant Heslov, along with Jean Doumanian, Steve Traxler and Claire Rudnick Polstein, the film will go before the cameras in September. No release date has been set.

August: Osage County tells the story of the Weston family, who reunites at their rural Oklahoma homestead when Beverly, the alcoholic patriarch, goes missing. Streep will play Violet, the pill-popping and deeply troubled mother of the family. Roberts is set to play Barbara, Violet’s daughter, and Breslin will play Barbara’s daughter Jean. Martindale will take on the role of Violet’s sister, Mattie Fae and Lewis will be paired with Mulroney as Karen, the chipper (if deluded) youngest daughter. August: Osage County originally premiered at Chicago’s Steppenwolf Theatre Company, then transferred to Broadway on December 4, 2007, taking home the 2008 Tony Award for Best Play. August: Osage County ended its Broadway run June 28, 2009.

Mulroney starred in My Best Friend’s Wedding opposite Roberts. His additional film and TV credits include Young Guns, New Girl, Bad Girls, The Thing Called Love, The Grey, About Schmidt, Zodiac, Struck By Lightning, Jolene, Must Love Dogs, Friends and How to Make an American Quilt. He appeared off-Broadway in The Sad Lament of Pecos Bill on the Eve Killing His Wife’s Killer’s Head/Action.
