Last night, we reported that the first trailer for Avengers: Age of Ultron will debut during next week's episode of Marvel's Agents of S.H.I.E.L.D., airing Tuesday, October 28 at 9 PM ET on ABC. If you can't wait that long to get your first glimpse at this Marvel Phase Two adventure, two images have leaked from the first trailer, which feature the massive Hulkbuster armor, which was teased in new promo art from last week, and the villainous Ultron himself.While it isn't clear exactly where these images came from, Screen Crush reports that they debuted on Twitter.
