The first trailer for Marvel's Avengers: Age of Ultron will debut on next week's episode of Marvel's Agents of S.H.I.E.L.D., Marvel Studios announced today. The teaser trailer for Avengers 2 will debut next Tuesday, October 28, at 9/8c on ABC. Attendees at this past summer's San Diego Comic-Con were treated to an extended sizzle reel for the Joss Whedon-directed sequel, so if the trailer includes any of that footage then fans should not be disappointed. Tune in to #Marvel’s #AgentsofSHIELD, Tuesday, October 28, 9|8c on @ABCNetwork to see the #AgeofUltron trailer on TV!
