Avengers: Endgame is nearly upon us, with the climactic chapter of "The Infinity Saga" set to wrap on April 26th. Now, with the cast in the process of hitting the press circuit, Chris Hemsworth has taken a moment to indulge in a little bit of side-vandalism. Channeling the mischevious nature of his cinematic brother Loki, Hemsworth whips out the sharpie and gets to work on sprucing up several of his castmates' posters. 

"I'm making some improvements," he quips in deadpan fashion, adding a crude mustache to Paul Rudd's Ant-Man. Chris Evans' Captain America gets a monocle-goatee combo, while Robert Downey Jr's Iron Man gets transformed into a Thor-loving SoundCloud rapper. Jeremy Renner's Ronin gets some dashing new eyelashes, and it might have gone further had Renner not intruded upon the scene. 

Check out the charming footage below, courtesy of Chris Hemsworth's own Instagram page. Seems like the cast is having a good time this promotional cycle, and it will be a shame if this truly if their last go-around. Perhaps, if Endgame actually lives up to the massive hype, it'll all be worth it.
