August: Osage County, fresh from its 2008 Tony Award wins for Best Play, Best Direction, Best Scenic Design and Best Leading and Featured Actress, get five new cast members at the Music Box.

The Tony wins of leading actress Deanna Dunagan and featured actress Rondi Reed coincided with the end of their contracts. They left the lauded Broadway run June 15, the same day they took home Tony Awards for Leading Actress and Featured Actress in a Play, respectively.

Academy Award winner Estelle Parsons succeeds Dunagan as pill-addicted matriarch Violet Weston in the comedy-infused drama by Tracy Letts. Molly Regan succeeds Reed as Violet's blowsy sister, Aunt Mattie Fae.

Also stepping into the rambling Oklahoma house of August on June 17, as previously announced, are Jim True-Frost as the new Little Charles (Mattie Fae's 37-year-old son), succeeding Ian Barford; Tony winner Frank Wood (Side Man), succeeding Jeff Perry as Bill, Violet's son-in-law, who is married to daughter Barbara, played by Tony nominee Amy Morton, who remains; and Robert Foxworth ("Falcon Crest," Proof on tour), succeeding Francis Guinan as Mattie Fae's husband Charlie.

Directed by Anna D. Shapiro (who won the Tony, Drama Desk and Outer Critics Circle Awards for her work here), Letts' Pulitzer Prize-winning August: Osage County is the "explosively funny comedy-drama focusing on the Weston family following the disappearance of the family's patriarch." *
