Factual error: When Hanh is fighting Williams, Williams throws a side kick to Hanh. Then he lifts up his hand to block - supposedly a metal hand - but his hand does not move one bit. It is not possible, due to that kind of force, for a hand to not move. Even if a hand is metal, the elbow will pivot. As well as the fact that after the kick, you see Williams' face is in pain. This is not possible as he is wearing soled shoes and kicking side on.
