The project, which would make Chase’s first series since his groundbreaking HBO mob drama, will be based on the non-fiction book Project Mind Control: Sidney Gottlieb, the CIA, and the Tragedy of MKUltra by author John Lisle. Chase has optioned the book and will write the adaptation which falls under the first-look deal his company Riverain Pictures has at HBO.

Project: MKUltra is a dramatic thriller centered on the infamous chemist and spymaster Sidney Gottlieb, often known as The Black Sorcerer, who headed the CIA’s MKUltra Psychedelic program which conducted dangerous and deadly mind control experiments on willing – and unwilling – subjects during the height of the Cold War. Gottlieb is also known as the unwitting godfather of the entire LSD counterculture.
