Theodore Shapiro has signed on to score the upcoming coming-of-age comedy drama St. Vincent. The movie is directed by Theodore Melfi and stars Bill Murray, Melissa McCarthy, Naomi Watts, Chris O’Dowd, Terrence Howard and Scott Adsit. The movie follows a cranky war veteran who becomes an unlikely mentor to a 12-year-old boy whose parents have divorced. Melfi has also written the screenplay, which was black listed in 2011 under the title St. Vincent de Van Nuys. Peter Chernin (Rise of the Planet of the Apes, The Heat) is producing the Chernin Entertainment production with Fred Roos (The Outsiders, The Black Stallion). Don Cheadle and Kay Liberman (House of Lies, Traitor) are executive producing the project for Crescendo Productions.
