The Russo Brothers are currently hard at work in Atlanta shootingAvengers: Infinity WarandAvengers 4, a shoot that is expected to take most of 2017 to complete. The next twoAvengersmovies are going to be the culmination of 10 years worth of theMarvel Cinematic Universe, which will see the Marvel heroes fighting their greatest foe yet; Thanos. Now, Marvel Studios has released a brand new, behind the scenes video, giving us our very first look atAvengers: Infinity War, and it is amazing.

Marveldropped the video online out of nowhere, completely surprising fans with their first look at the upcomingAvengers: Infinity WarandAvengers 4. It may not be a trailer, but it is easily the next best thing and is more than enough to get MCU fans extremely excited. In the video, Marvel Studios PresidentKevin Feigehad this to say about finally bringing Thanos properly into the fold and what that will mean for Earth’s mightiest heroes.

“For us, the important thing is making it all come together. We know they’re gonna face Thanos. We’ve been setting that up since Avengers 1. How do you do that in a way that is unexpected that pits the Avengers against somebody who is more powerful than anybody they’ve faced and yet make them completely unprepared to face them? Well, you tear them apart, and that’s why we did Civil War beforeInfinity War.”

As exciting as it was to see theCivil Warstoryline finally tackled on the big screen, it is really interesting to realize that was an intentional part of what will make Thanos an even bigger threat when he finally assembles all six Infinity Stones together. AsKevin Feigeputs it, “Thanos shows us why he’s the biggest, the best, the baddest villain that we’ve ever had.” As an added bonus, the video gives us a new look atJosh Brolin as ThanosinAvengers: Infinity Warand it is truly stunning and makes it seem like it is going to be worth building him up since the post-credits scene inThe Avengersback in 2012.

Outside of helping us realize just how big of a threat Thanos is going to be, the video gives us looks at some of the sets, a little bit of insight into how the Russo Brothers thoughts on the movie, as well as some of the cast and crew on set. Perhaps most delightfully, we get to seeRobert Downey Jr.,Tom HollandandChris Prattall hanging out on set together, which points toward getting to see Iron Man,Spider-Man and Star-Lordall sharing the screen at the same time. That is something comic book fans probably never thought they would be seeing on the big screen.
