Avengers: Endgame has hit theaters like The Hulk hitting a brick wall. The film has smashed box office records by bringing in $1.2 billion worldwide on its opening weekend. Seeing as Endgame is the final installment of the original movie franchise, the release has left both the fans and the cast members feeling a little emotional.

Since the actors can't share anything that's even remotely a spoiler, most of the cast chose instead to share some funny and heartwarming behind the scenes photos from their time in the Marvel Comic Universe. Don't worry. There are NO spoilers ahead, just heartbreak.

There was one cast member who broke all the rules when they posted a very illegal behind-the-scenes video.

A6 Assemble

Jeremy Renner got Marvel fans stoked when he posted this photo more than a month before the premiere of Endgame. Renner posted the fun selfie with the caption "Dear Thanos, we're coming for you... sincerely A6!"

With a photo and caption like that, it's hard not to get stoked for the film. Considering the fact that this is supposed to be the last time the original six Avengers band together to save the world, this photo means even more.
