Chris Evans has a history of surprising his costars on The Ellen DeGeneres Show. During the Avengers: Age of Ultron press tour, he snuck out on stage during Scarlett Johansson’s interview with DeGeneres to scare her, and when he and Elizabeth Olsen stopped by the show for Monday’s episode, he pranked his Captain America: Civil War costar by hiding in her dressing room bathroom.
But this time around? Evans got a taste of his own medicine.
DeGeneres first lulled Evans into a false sense of security by sharing an earlier clip of him scaring Olsen. But shortly thereafter, an Ellen staffer dressed like Iron Man popped out to give Evans a surprise of his own. (Olsen, for her part, was stonefaced the second time around.)
Watch the clip below to see both Olsen and Evans’ reactions.
Captain America: Civil War opens on May 6.
