Eastwood is known for his economical film shoots; his regular camera operator, Steve Campanelli, indicated the rapid pace at which Eastwood films—and his intimate, near-wordless direction—also featured during "Changeling"s shoot. Eastwood limited rehearsals and takes to garner more authentic performances. Jolie said, "You've got to get your stuff together and get ready because he doesn't linger ... He expects people to come prepared and get on with their work." Campanelli sometimes had to tell Jolie what Eastwood wanted from a scene, as Eastwood talked too softly. To provide verisimilitude to certain scenes, Eastwood sometimes asked Jolie to play them quietly, as if just for him. At the same time he would ask his camera operator to start filming discreetly, without Jolie's seeing it.
