The Internet pretty much exploded last week when Marvel debuted an awesome first teaser trailer for Joss Whedon’s Avengers: Age of Ultron, the writer-director’s anticipated sequel, following on from 2012’s epic game-changer. Then it nearly went again last night as the Marvel event kicked off unveiling what the studio have planned for the next 6 years! If you missed that, check out our roundup here and the ten things we learnt from the annoucements.

The trailer was originally set to be attached to this week’s episode of Marvel’s Agents of S.H.I.E.L.D., but after leaking early, the studio instead decided to air a different exclusive during the episode, and it teases plenty to get excited about too.

Marvel Studios presents Avengers: Age of Ultron, the epic follow-up to the biggest Super Hero movie of all time. When Tony Stark tries to jumpstart a dormant peacekeeping program, things go awry and Earth’s Mightiest Heroes, including Iron Man, Captain America, Thor, The Incredible Hulk, Black Widow and Hawkeye, are put to the ultimate test as the fate of the planet hangs in the balance. As the villainous Ultron emerges, it is up to The Avengers to stop him from enacting his terrible plans, and soon uneasy alliances and unexpected action pave the way for an epic and unique global adventure.

Robert Downey, Jr., Chris Evans, Chris Hemsworth, Mark Ruffalo, Scarlett Johansson, and Jeremy Renner reprise their leading roles, with Elizabeth Olsen, Aaron Taylor-Johnson, Paul Bettany, Samuel L. Jackson, Cobie Smulders, and James Spader completing the cast nicely.

Avengers: Age of Ultron will be released on April 24th, 2015 in the UK and May 1st on the other side of the Atlantic.
