Eric Roth, who wrote Shepherd (as well as Forrest Gump and Munich) and is now at work on an adaptation of Bearden's Cold War memoir, The Main Enemy, makes no apologies for dramatic license in spy movies. "Milt is very intelligent and he knows where all the bodies are buried," says Roth. "But what is best for the sense of the piece may not always be factually accurate. We're not making a documentary."
Roth is also the screenwriter behind such gems as The Postman
and Benjamin Button
