Warner Bros. has purchased Unlocked, a spec script by Peter O’Brien, reports Variety.
The story is said to focus on a CIA interrogator, whose mistake puts her in the middle of terrorist plot to launch a biological attack on London.
Lorenzo di Bonaventura (G.I. Joe: The Rise of Cobra, Transformers) and Georgina Townsley (the 2005 documentary, Diameter of the Bomb) will produce.
O’Brien previously worked on the video game Halo: Reach.
