And we thought striking terror was Batman's gig.
Earlier this week on The Ellen Show, Captain Americaactor Chris Evans gave a star-spangled scare to his Avengers: Age of Ultron co-star Scarlett Johansson. Sneaking up on Johansson as she sang Evans' praises, Evans grabbed her shoulders from behind and bellowed a startling "Boo!" in her ear. Johansson may want to think twice about complementing Evans in the future.
Check out the video below. We just hope this doesn't convince Black Widow to join Iron Man's side in next year's Civil War.
Avengers: Age of Ultron hits theaters tomorrow, May 1. For ComicBook.com's official review of the film, head here.
