“You want a killer? Here he is.” New trailer for the Dylan O’Brien-led action thriller proves it takes one to kill one. AMERICAN ASSASSIN follows the rise of Mitch Rapp (Dylan O’Brien), a CIA black ops recruit under the instruction of Cold War veteran Stan Hurley (Michael Keaton). The pair are then enlisted by CIA Deputy Director Irene Kennedy (Sanaa Lathan) to investigate a wave of apparently random attacks on both military and civilian targets. Together the three discover a pattern in the violence leading them to a joint mission with a lethal Turkish agent (Shiva Negar) to stop a mysterious operative (Taylor Kitsch) intent on starting a World War in the Middle East. Irish release date is September 15, 2017.
