With Batman v. Superman done, Captain America: Civil War is ramping up promotions. The latest trailer shows Steve Rogers a.k.a. Captain America and Tony Stark a.k.a. Iron Man fighting for their sides. With Cap thinking that the "safest hands are still our own" and Iron Man doing "what has to be done to stop something worse." And someone seems to be playing both sides, if this new trailer is any indication. What do you think?
