At the end of the Iraq War in 2007, two soldiers (Aaron Taylor-Johnson and John Cena) are caught between a rock wall and a hard place when they're pinned by a legendary Iraqi sniper known for his laser accuracy and high kill count in The Wall, opening May 12. It's a smaller film in limited release that's directed by Doug Liman, no stranger to creating taut action sequences thanks to his work on the Bourne movies and Edge of Tomorrow. In this clip, the first released, watch John Cena take aim -- and fire.
