Spitfire Pictures has optioned Richard Rhodes' nonfiction book Deadly Feasts to use as the basis for a thriller to be written by "Glory Road" scribe Christopher Cleveland, according to Variety. "Deadly Feasts" will be produced by Spitfire partners Guy East and Nigel Sinclair. Cleveland will exec produce with Howard Blum. Rhodes, the Pulitzer Prize-winning writer of "The Making of the Atomic Bomb," wrote about scientific sleuths attempting to discover the cause of mad cow disease, a brain disease that proved similar to a fatal virus seen in tribes in New Guinea in the 1950s. The common thread turned out to be cannibalism: The tribes engaged in it, and the cattle got fed ground-up animal parts. "This is a real-life thriller set in today's America," Sinclair said.
