Boston University has been caught up in a messy fight over a collection of papers, videotapes and film reels of the independent filmmaker Mark Rappaport, The Boston Globe  reported. Rappaport gave the materials to Ray Carney, a film professor at BU, in 2005. But Rappaport said he believed that he was turning over the materials for storage while he was going to be out of the country. But Carney has treated the agreement as a gift of the materials to him. With many film luminaries signing a petition  demanding that Carney return the materials, some faculty members at BU fear that the reputation of their film program is being hurt by the dispute.
