Cynthia Littleton Business Editor “Blonde” producer Plan B Entertainment is looking for a new blueprint. The production banner run by Brad Pitt and Dede Gardner has tapped Moelis & Co. to shop for a buyer or potential investors. The company has a first-look deal for TV with Amazon Studios and a pact with MGM Studios for film. Reps for Moelis & Co. declined comment. Reps for Plan B could not immediately be reached for comment. Plan B was hatched in late 2001 as a partnership between Pitt and actor Jennifer Aniston, about four months after the two were married in July 2001. Pitt eventually took over the venture after the pair split in 2005.
