The Avengers: Age of Ultron’s final trailer was released Wednesday, giving fans incredible new looks at the cast, including our first look at The Vision. New behind-the-scenes videos include cast interviews and additional footage.

The final Avengers: Age of Ultron trailer stuffed just about every incredible scene we could imagine into one trailer, and we finally saw The Vision. He showed up near the end, and fans seemed very excited to see the mysterious character.

Today, ET has released two videos which show some behind-the-scenes looks of their set visit, and some cast interviews where Robert Downey Jr., Chris Hemsworth, Cobie Smulders, Jeremy Renner, Chris Evans, and Mark Ruffalo, joke about how they can’t really say anything about the movie.

Despite the fact that we’re less than two months away from The Avengers‘ sequel, the cast are staying tight-lipped, and aren’t revealing anything we don’t know already. Renner has a funny moment in one video, where he explains how he doesn’t slip up, saying, “I keep myself in the dark, you mean I shoot a bow and arrow?”

There are some other great moments with RDJ and Hemsworth, and the other two videos give us some behind-the-scenes looks with Age of Ultron’s director, Joss Whedon, and he talks a bit about making Marvel’s most highly anticipated sequel to date. We also get an inside-look into the props department, which is pretty amazing. Check out the videos below thanks to ET and Cineplex:

The Avengers: Age of Ultron’s first trailer was incredibly well received, with a much darker tone than expected, and the second trailer followed a similar path. The third, and possibly final, trailer continues the dark tone, but certainly ramps up the excitement.

Expect an enormous amount of promotion for Avengers: Age of Ultron during the next two months, as we approach the film’s worldwide release on May 1. The Avengers’ sequel may very well be the most anticipated sequel of all time, especially for Marvel fans, and the studio will be going all out with Age of Ultron promotion over the next few weeks.

The Avengers: Age of Ultron will be released in theaters on May 1, 2015, with its follow-up being Avengers: Infinity War, which has been split into two parts and will be directed by Anthony and Joe Russo.
