Marvel Studios Released A 10th Anniversary Class Photo Including Every Single Hero

It's been exactly 10 years since the crazy train that is the Marvel Cinematic Universe left the station.

With the first Iron Man film the franchise took off at a break-neck speed, and hasn't stopped since.

And today Marvel Studios released a behind-the-scenes video of a celebration which took place last October in honor of this achievement, where every single actor in their films gathered for a class photo.

The class photo itself is already an ICONIC work of art:

In the clip released by Disney showing the behind-the-scenes of the photo shoot, “Thor’s” Hemsworth said, “It felt like being at the Academy Awards or something. Every person had been in one or all of my favorite films.”

“There’s a ton of fan-boying and fan-girling going on in that room with each other,” Cheadle added, who has played War Machine in a number of Marvel films.

“Iron Man’s” Downey Jr., featured prominently in the class photo, said, “I literally am dead-center in the front row and I’m looking around going, ‘Any one of these people could be dead-center.'”

The photo kicks off Marvel’s 10-Year Sweepstakes, which will take place across social media and last from Feb. 8 to March 15. A winner will be selected each week to receive an “Ultimate Marvel Fan Prize” package, which includes a visit to the “Captain Marvel” set and a tour of Marvel Studios.

Marvel is celebrating its most recent release “Black Panther,” hitting theaters Feb. 16, but the studio’s 10th anniversary will officially begin with the release of “Avengers: Infinity War” on May 4.
