Dylan O’Brien has had his share of difficult scenes when shooting scenes from his upcoming movie, “American Assassin.” The “Teen Wolf” actor stars in the action-packed movie as Mitch Rapp, a CIA black ops recruit under the instruction of Cold War veteran Stan Hurley (Michael Keaton). 

Rapp and Hurley are 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.

O’Brien had to do a lot pf prep for the role. Check out this featurette video on O’Brien below:
