ER reunion alert!  Well, sort of.  George Clooney and his producing partner Grant Heslov have signed on to produce longtime ER showrunner John Wells’ impressive next directorial feature, August: Osage County.  The film is based on the Pulitzer/Tony Award-winning play by Tracy Letts and follows “the women of a family whose lives have splintered in many directions until a crisis bring them back to their childhood home and to the dysfunctional woman who raised them.”  The Weinstein Company is backing the pic, which is set to star Meryl Streep as the family’s pill popping matriarch and Julia Roberts as her daughter.

Though he’s directed numerous television episodes (including ER and The West Wing), Wells made his feature directorial debut with 2010’s The Company Men.  Casting for August: Osage County is ongoing, but Clooney and Heslov make yet another impressive addition to this promising production.  Filming is set to get underway this fall, so expect Streep’s name to be among the 2013 Best Actress nominees.  Hit the jump to read the press release.
