Lesley Barber is reteaming with director Kenneth Lonergan on the upcoming drama Manchester by the Sea. The film stars Casey Affleck, Michelle Williams, Lucas Hedges and Kyle Chandler. The movie follows a man who is forced to return home to care for his 16-year-old nephew after brother passes away and is compelled to deal with a tragic past that separated him from his family and the community where he was born and raised. Lonergan has also written the screenplay. Matt Damon is producing the project with Lauren Beck and Chris Moore (American Pie series, Promised Land, Joy Ride). Barber has previously composed the music for Lonergan’s first feature, You Can Count on Me. The director’s last film, Margaret, was scored by Nico Muhly. Barber’s other previous scoring credits include Mansfield Park, When Night Is Falling and The Moth Diaries. Manchester by the Sea is set to premiere next month at the Sundance Film Festival.
