Last week the first trailer for Avengers: Age of Ultron was leaked. It was meant to be debuted on this week's episode of Marvel's Agents of S.H.I.E.L.D. Marvel had no choice but to officially release the trailer but did promise extra footage when the episode aired.
Now Marvel has gone one step further and made the new-ish trailer available for us to share with all of you. The first part is the footage that was shown at SDCC.
