Variety reports the pair have grabbed roles in an Off Broadway production of Anton Chekhov's Uncle Vanya, which will hit the stage next year. The twist in this news -- they're both grabbing roles, but they're not playing lovers. Gyllenhaal will play Yelena, while Sarsgaard plays doctor Astrov. This means that she'll play the new, young wife of Serebrakov (the 70+ George Morfogen ... a coupling I bet you didn't see coming!). Also in the cast are Meryl Streep's daughter, Mamie Gummer, and Denis O'Hare (the man who watched the infinite abyss in Garden State) as Uncle Vanya. Just to make it all the more tantalizing -- Austin Pendleton (Catch-22, Short Circuit) is directing it.
New York residents should definitely keep an eye out for it, and the rest: head to the Big Apple and make it a Dawes-on-stage double feature -- Katie v. Maggie, the final decision. I'd rather suggest you see Peter and Maggie's short film High Falls, but it doesn't seem to be available on DVD or online.
