Chris Evans and Robert Downey Jr. duked it out in a thumb war at the Kids’ Choice Awards, Anthony Mackie loves his karaoke jams, and Chris Pratt isn’t afraid to strut his stuff in heels. In short, the Marvel actors are a bunch of goofballs, but there’s no bigger goofball than Paul Rudd.

Marvel’s resident Ant-Man assisted Captain America: Civil War directors Joe and Anthony Russo in revealing Evans’ reaction to seeing the finished film. “It’s a very stressful moment for directors to show the star the movie for the first time,” Anthony Russo said in the video posted to Facebook. In the end, the actor was revealed to be Rudd hiding behind a cut-out mask and Cap’s shield.

Rudd reprises his role of Ant-Man for Civil War and joins Team Captain America in their fight against Team Iron Man. After another international incident involving the Avengers, the governments of the world introduce the Sokovia Accords, which seek to enforce harsher restrictions on superhumans. The action divides Earth’s Mightiest Heroes and ignites a war between allies.

James Gunn, the writer and director behind Guardians of the Galaxy, Vol. 2, is one of the lucky few who’ve already seen the film, calling it “one of the best Marvel movies ever.”

Captain America: Civil War hits theaters on May 6.
