The Office of the U.S. Trustee and private equity investor Palm Beach Capital say that Digital Domain Media Group is a corporate shell that is trying to sell what is left and pushing a settlement with unsecured creditors and top-ranking lenders, Dow Jones DBR Small Cap reported today. Once a prize-winning provider of special effects for movies such as "Titanic," Digital Domain collapsed on Sept. 11 and sold its operating business in a high-speed bankruptcy sale.
