British actor Emily Blunt (The Devil Wears Prada), is set to join Susan Sarandon in playwright David Auburn's The Girl In The Park, according to Production Weekly.
Auburn who wrote the script will make his directorial debut on the film.
Enduringly traumatized by the disappearance of her 3 year old daughter 15 years ago, Julia Sandburg (Sarandon) has cut herself off from anyone once near and dear to her, including her ex-husband Doug and her son Chris, who tried for years to penetrate her wall of isolation and despair, without success. But when Julia meets Louise (Blunt), a troubled young woman with a checkered past, all Julia's old psychic wounds painfully resurface, as does her illogical and increasingly irrational hope that Louise may be the daughter she lost so long ago.
Auburn is best known for his 2000 play Proof. It won the 2001 Tony Award for Best Play, as well as the 2001 Pulitzer Prize for Drama. His most recent work is the screenplay for the Keanu Reeves and Sandra Bullock drama The Lake House.
Filming is scheduled to begin filming this autumn in New York.
