DreamWorks Animation SKG named Tom Freston to its board of directors today. The former Viacom Inc. president and CEO, who OK’ed the deal to bring DreamWorks into Paramount, was axed by old coot Sumner Redstone a year ago. Nothing like having a common enemy to bring Hollywood types closer together. I should also remind you that, within hours of Freston’s firing before his body was even cold, David Geffen called up Redstone and suggested Jeffrey Katzenberg take Tom’s place. But Redstone said fuhgeddaboudit.
