It's like we always say here at Vulture: There's no such thing as too much Chekhov. Peter Sarsgaard is following his performance in Broadway's The Seagull with a turn as Astrov in the playwright's Uncle Vanya. But, wait, it gets better: The role of Yelena will be filled by none other than … Maggie Gyllenhaal! Reports Playbill: "The real-life couple join Tony Award winner Denis O'Hare as Vanya, Mamie Gummer as Sonya, Louis Zorich as Waffles, George Morfogen as Srebryakov, Delphi Harrington as Maria and Cyrilla Baer as Marina." Previews begin January 17 at Classic Stage Company. [Playbill]
