To their credit, Marvel Studios has been holding back on revealing too much when it comes to Avengers: Age of Ultron and its story by Joss Whedon who returns to the director’s chair after helping the first become the most successful superhero film of all-time, and the third biggest at the worldwide box office. We had the opportunity to chat with Whedon and the cast while visiting the Avengers 2 set last summer but even then, everyone involved was guarded and tight-lipped. The message is clear: no spoilers.

We’ve done our best to piece together details from the marketing assets, interviews, merchandise, tie-in comics and even Marvel’s future plans for the franchise, but there’s still so much we don’t know which is what has brought anticipation for a new official trailer to an all-time high. That new tease, the third official U.S. Avengers: Age of Ultron trailer, is finally here.

Unlike the second trailer which placed the spotlight on Hulk, this third variant features mostly new footage, including more of the turmoil between Earth’s Mightiest, background on how Stark is responsible for Ultron, and of course, the team fighting together and against each other. And yes. there’s the first look at Vision, however brief, right at the end.

Did you catch the scene of Quicksilver punching out Captain America using super speed? Scarlet Witch mind-controlling Black Widow? Hawkeye taking out a crowd of Ultrons with a flame arrow?

The Vision is a character writer and director Joss Whedon desperately wanted to introduce into the MCU since he began work on the first Avengers film. While Paul Bettany, previously the voice of Iron Man’s A.I. assistant J.A.R.V.I.S. wouldn’t give us details on his role or even his contract length with Marvel when we spoke with him at Comic-Con International, some rumors point to the character reappearing in Captain America 3 (even before it was officially given the subtitle Civil War and revealed that Robert Downey Jr. would be starring) and having a major role to play for years to come.

Vision’s origins remain largely a mystery and while it seemed he was created by Ultron in the movie as he was in the comics, marketing materials suggest that Bruce Banner and Tony Stark might be responsible for creating him, if not, helping program him. It’s especially confusing since when were on set, we watched Thor and Vision fighting one another. For more on that and other in-depth details, check out our set interviews (more still to come!):
