The spec is drawn from a true story. An American diplomat in Kazakhstan after the fall of the Soviet Union discovers a massive stock of enriched uranium, and it’s a race against time to get it out of the country before potential terrorists get to it first. Gunn is currently a writer and producer on Designated Survivor, the ABC drama that stars Kiefer Sutherland, and before that he wrote on the Starz series Black Sails, The Whispers and HBO’s The Newsroom. Gunn previously sold the 2015 Black List script The Virginian to New Line with Bradley Cooper attached to play young George Washington. Gunn is repped by Principato-Young Entertainment, WME and attorney, David Fox.
