Watch Chris Evans Goof Around As Old Man Cap On The Avengers: Endgame Set

Avengers: Endgame might have been a pretty serious epic, but some of its stars still found time to goof off on set.

After holding an Instagram Live event to celebrate the one-year anniversary of Endgame's record-smashing arrival in theaters, the film's directors, the Russo brothers, took to Twitter to make their way through the three-hour film. As they watched, they posted behind-the-scenes tidbits and pieces of trivia about making the film, from the story behind one of Captain America's (Chris Evans) most impactful lines to hidden Easter eggs you might never have noticed. 

Beyond that, they also released some behind-the-scenes footage of the actors' last moments on set and their reactions to some of the film's biggest moments, and some of those takes turned out to be a bit silly. One of them, featuring Evans playing around on set in his serious old man makeup, is pretty delightful – during the rewatch, the Russos posted the clip on Twitter with the caption, "See...he's not that old..."

Captain America's happy ending

By the end of the film, the Avengers have saved the world from Thanos for good thanks to a clever mix of time travel and a fateful snap of the Infinity Gauntlet performed by Tony Stark (Robert Downey Jr.), though the effort costs him his life in one of the film's saddest scenes. In the denouement, the team is free to settle wherever they'd like throughout time and space, leading to an emotional ending for Steve Rogers.

After replacing several of the Infinity Stones in the timelines where they belong to ensure nobody can ever "snap" away half of all living beings again, Captain America finally gets his happy ending with the love of his life, Peggy Carter (Hayley Atwell). As he returns to greet his friends and let them know where he went, as well as pass on the title of Captain America to Sam Wilson (Anthony Mackie), he appears as an old man, making Chris Evans look positively ancient.

Steve's clearly still pretty spry for a senior citizen, however, as, in the clip, he playfully races around and throws a rock like a baseball as the crew giggles at Evans' antics. Clearly, even in one of the film's big emotional set pieces, Evans could still find a way to make everybody on set laugh.

It might be hard to believe that it's been a whole year since Endgame's release, but any time you want to relive the epic battles and emotional high points, you can go ahead and stream the entire film on Disney+.
