Casting continues for Rogue Pictures’ thriller The Dark Fields as Anna Friel (Land of the Lost, “Pushing Daisies”) is in negotiations to join the previously announced casting of Bradley Cooper, Elizabeth Banks and Robert De Niro. Penned by Leslie Dixon, the story centers on a down-and-out writer (Cooper) who gets his hands on a top-secret pharmaceutical drug that makes one smarter. He experiences sudden financial and social success but soon discovers that the drug has lethal and lasting side effects, including “trip-switching,” a phenomenon in which time moves with a stop-motion quality. Before long, mysterious antagonists are pursuing him. Friel will play Cooper’s ex-wife, a woman who was a go-getter before their breakup. Neil Burger will direct the Relativity produced thriller.
