Christopher Walken has been forced to pull out of a theatrical reunion with his The Deer Hunter co-star Meryl Streep due to conflicting schedules. The actor signed on to play THE COOK in The Public Theater's MOTHER COURAGE + HER CHILDREN in Central Park, New York City, last month (JUN06), but has since quit the project. He'll be replaced by Streep's SOPHIE'S CHOICE co-star Kevin Kline. The BERTOLT BRECHT play will debut at the Delacorte Theater on 8 August (06). The play marks Kline's first stage performance since he was inducted into the Theatre Hall Of Fame. The actor is also set to play King Lear in the Public Theater's production of the classic William Shakespeare tragedy later this year (06).
