An interview by ET with Margo Martindale, mentioning “August: Osage County” as well:
ETonline: You’re currently expericning the other side of the coin, working on the cinematic adaptation of August: Osage County. How much of that play has been “movie’d up?”
Martindale: It’s beautiful. So beautiful. I think it really retains the spirit of the film. Tracy Letts (who wrote the play) wrote the screenplay so he kept it really close to the play. He’s opened up some of it, but most everything takes place in the house. I absolutely loved working with Chris Cooper, Meryl [Streep], Benedict [Cumberbatch], Julia [Roberts]; everybody was wonderful.
