12 Interesting Age Of Ultron Theories Based On The Trailer

11. It'll Plant The Seeds For Civil War

The global catastrophe caused by Ultron - an invention of Tony Stark's - will likely be the trigger that causes Tony Stark to get on side with the Superhuman Registration Act. Full of guilt after the devastation Ultron will cause in this movie, he will want all superhuman activity to be monitored, leading him to be the figurehead of the pro-registration forces. Likewise, the trailer is showing friction between him and Thor, signalling what we believe to be the first formal split that will be reflected in the two Civil War sides - with Thor opting to oppose Tony by joining the anti-registration side alongside Captain America.
