Captain America Kicks Iron Man’s A** In Captain America: Civil War Trailer

Iron Man and Captain America go toe-to-toe in the epic first trailer for Captain America: Civil War.
The delicate relationship between civilians and superheroes/superpowered individuals is a concept that has been depicted in almost every Marvel movie. Humans are naturally fearful of the unknown and it is this fear and anxiety that has led to the creation of the Superhero Registration Act that requires potential heroes to prove their good-will by registering and working under strict supervision, following the events of Avengers: Age of Ultron when the city-state of Sokovia was literally ripped off the face of the earth.
Steve Rogers, who discovered the corrupt nature of S.H.I.E.L.D in Captain America: The Winter Soldier, has lost all faith in the government. Tony Stark, who recklessly unleashed Ultron upon the world, is in favor of the act and is willing to go head-to-head with Captain America, who is opposed to the act, to ensure that he complies with the government accord. Aside from opposing such an act, Rogers also wants to protect his friend Bucky Barnes (Sebastian Stan) who was brainwashed into becoming the evil Winter Soldier.
