FILE - In this Aug. 13, 2012 file photo, Shia LaBeouf attends a screening of "Lawless" hosted by The Weinstein Company and The Cinema Society in New York. LaBeouf appears completely nude in Sigur Rós' new music video in Lars Von Trier's “The Nymphomaniac." LaBeouf can next be seen in “Lawless,” opening Wednesday, about a West Virginia moonshine business during the Prohibition era.
