Aaron Taylor Johnson is starring alongside wrestler, John Cena in the new war film 'The Wall', which follows two soldiers pinned down by an Iraqi sniper with nothing but a crumpling wall between them and their adversaries. The British actor was blown away by his co-star's many talents. Speaking to Collider, Aaron said: "He's incredible. I don't think anybody can prepare for the expectation of what you think John would be like, but he's a remarkable person. He's very funny and he's very smart.
