In the second official trailer for The Great Wall, we're taken to the stunning mountainous regions of ancient China. We see Matt Damon in battle gear and hear a man say, "We've travelled thousands of miles in search of a weapon more powerful than we've ever known."
Shortly after, we see brief battle scenes unfold before we're transported to the Great Wall. Matt's character discusses a trade agreement with a Chinese woman, he's called a thief and he's locked up. Then, we see a creature ascend the Wall and pull a man down below. We're informed that "the Great Wall is the only barrier keeping the world safe." A war between humans and the monstrous creatures that threaten their existence begins to take shape and Matt's character is positioned as a crucial player in the survival of mankind. The trailer also features an appearance by Willem Dafoe.
