Marvel's Avengers: Age of Ultron Teaser Trailer is Here
This is the trailer that was supposed to premier next week during Agents of S.H.I.E.L.D., but it was leaked a bit early. Marvel then went ahead and officially posted it on YouTube, after heading to Twitter and ousting the group behind the leak.
Dammit, Hydra.
