No, this isn't some bizarre spoiler for The Avengers: Age of Ultron. Hawkeye actor Jeremy Renner apparently stuck Scarlett Johansson's stunt double's mask on his own face, and the effect is...really strange.

Now I won't be able to get this image out of my head when Hawkeye and Black Widow appear on screen together. Thanks, Renner.
