The “Avengers: Age of Ultron” trailer was due to debut next week during an episode of “Marvel’s Agents of S.H.I.E.L.D.,” but a little leak gave Marvel fans something to gawk at a few days early.
After the leak, Marvel decided what the hey and added it to their YouTube channel. The trailer has since received more than 27 million views.
Marvel made light of the mishap and simply blamed Hydra.
