According to Playbill, Kevin Kline will play the role of the Cook opposite Meryl Streep in the Aug. 8-Sept. 3 Central Park staging of Brecht’s classic Mother Courage, Playbill.com has learned. He replaces the previously announced Christopher Walken. Walken left the production “due to scheduling conflicts,” according to the Public. Production dates will remain the same. Opening night is Aug. 21. The Kline and Streep casting brings with it echoes of the Public Theater’s 2001 revival of Chekhov’s The Seagull, which featured the two actors. The two are also well known for their pairing in the film “Sophie’s Choice.” Mother Courage will be the first of two Public assignments Kline will essay this year.
