AMC is adding to its drama roster, putting three more dramas into development: one about diamonds, one Indian gangsters, and another adaptation of a European cop show. Tony and Ridley Scott are set to executive produce the still-untitled gem-centric series from Before the Devil Knows You’re Dead writer Kelly Masterson. Diamond-y! Sacred Games (adapted from the novel) traces the intersecting stories of police officer and a gangster in Mumbai, and Low Winter Sun is based on the bleak, brutal British series of the same name about a two corrupt cops who kill another police officer. Just as long as they solve whatever case they’re working on, things will work out fine. [THR]
