Playbill caught up with the cast of and creative minds behind the new darkly-comedic film "August: Osage County" at a recent media junket. Based on Tracy Letts' Pulitzer Prize and Tony-winning play (with a screenplay by Letts himself), the film delves into the relationships of the strong-willed but troubled women of the Weston family, who are brought together when the family's patriarch is found dead. Here, cast members Julia Roberts, Abigail Breslin and Dermot Mulroney chat about the experience of working with the legendary Meryl Streep. The film opens in New York and Los Angeles on December 27.
