Julia Roberts, Meryl Streep confirmed for August: Osage County film

Harvey Weinstein made it official this evening: Julia Roberts and Meryl Streep are attached to take on the fiery mother-and-daughter duo Barbara and Violet Weston in the film adaptation of August: Osage County.

The central roles of Tracy Letts's sprawling family drama were created by Amy Morton and Deanna Dunagan in the play's 2007 debut at Steppenwolf Theatre Company, and again on Broadway later that year. Both were nominated for the best actress Tony Award in 2008 (Dunagan won), while Letts won the best play Tony and the Pulitzer Prize for Drama, among many other accolades.

There's been talk of Streep and Roberts for the film since 2010, but now the rumors seem to be reality. A press release from the Weinstein Company quotes Roberts as saying, "After seeing Meryl Streep's mesmerizing portrayal as Margaret Thatcher in The Iron Lady, it has me even more excited and proud to costar with her," which I'm sure is a perfectly candid statement that came right out of Julia's mouth. John Wells is attached to direct; a recent L.A. Times post suggested the film could shoot this fall for an autumn 2013 release.
