William Monahan will write a fact-based thriller for Paramount, broadcasts Variety. The feature is inspired by an article that will run in Playboy later this year. “It’s the story of a drug dealer who traded a prison sentence to go undercover at a maximum security hospital for the criminally insane, where he tried to get a serial killer to divulge the whereabouts of his victims.” The untitled film will be produced by Graham King and Alexandra Milchan, with Joel Gotler executive producing.
