WARNING: The following article contains major spoilers for Avengers: Endgame, in theaters now.
Now that the highly-anticipated Avengers: Endgame is out in theaters, the movie's many, many secrets finally stand revealed.
In the film's third act, Hulk, Captain America, Iron Man and the remaining Avengers succeeded in bringing back everyone who had been dusted by Thanos in Avengers: Infinity War. An epic battle followed, in which all of the Marvel Cinematic Universe's superheroes took on Thanos' entire alien army for the fate of the universe.
Now, following the movie's record-smashing opening, Star-Lord himself Chris Pratt has shared a behind-the-scenes video he took during what appears to be a rehearsal for the film's climactic battle.
"I remember being blown away in this moment on the Avengers set," Pratt wrote in the video's caption. "Nobody was allowed to film anything on their phones. I said screw it. No rule was going to stop me from seizing this once in a lifetime opportunity to capture this collection of stars, a group that likely will never be in the same room again. We are so blessed."
As the camera pans in the video, we see almost all of the movie's stars gathered in the same spot: Dave Bautista, Don Cheadle, Elizabeth Olsen, Chris Evans, Paul Rudd, Chris Hemsworth, Jeremy Renner, Sebastian Stan, Chadwick Boseman, Mark Ruffalo, Pom Klementieff, Tom Holland, Danai Gurira, Robert Downey, Jr., Benedict Cumberbatch and Sean Gunn, the on-set double for Rocket, who jokes, "I'm pretty sure I'm the most famous person here."
"This is a really illegal video," Pratt confirms, before Captain America himself Chris Evans shows up to tell the Guardians of the Galaxy actor he is in big trouble.
Avengers: Endgame has just come out of an unprecedented opening weekend, which saw the film earn $1.2 billion worldwide in three days (including Thursday night previews) -- the first movie ever to do so.
Directed by Joe and Anthony Russo, Avengers: Endgame stars Robert Downey Jr. as Iron Man, Chris Evans as Captain America, Mark Ruffalo as Bruce Banner, Chris Hemsworth as Thor, Scarlett Johansson as Black Widow, Jeremy Renner as Hawkeye, Brie Larson as Captain Marvel, Paul Rudd as Ant-Man, Don Cheadle as War Machine, Karen Gillan as Nebula, Danai Gurira as Okoye and Bradley Cooper as Rocket, with Gwyneth Paltrow Pepper Potts, Jon Favreau as Happy Hogan, Benedict Wong as Wong, Tessa Thompson as Valkyrie and Josh Brolin as Thanos.
