The trailer of "Avengers: Age of Ultron" was scheduled to air on ABC's "Agents of S.H.IE.L.D" episode. The Marvel production house reportedly made the trailer release announcement recently, thus giving the audience one more reason to tune in to the show. However, the low resolution trailer has already been leaked online, and Marvel was quick enough to release the trailer officially. Now it remains to be seen whether Marvel would go ahead with its "Agents of S.H.I.E.L.D" tie in plans or not.

Before the trailer was leaked, ComicBook

reported that "Avengers: Age of Ultron" trailer will be shown after tonight's "A Hen in the Wolf House" episode of "Agents of S.H.I.E.L.D." The trailer has been tied in with "The Fractured Horse" episode, which airs on Oct. 28.
