"I was bored on the set. We were doing the scene with a stunt double and she wears this kind of mask and I wanted to wear it," Jeremy told Jimmy Fallon on "Tonight Show Starring Jimmy Fallon" on Tuesday. "It's creepy, right."

The "Hurt Locker" star suggested that if his character and Scarlett's character had a baby, the "creepy" photo would be a fairly accurate portrayal of what the baby would look like, with ripped muscles and a pale face highlighted with eyeliner.

"Hawkeye and Widow? Widow and Hawkeye??? Hmmm. #iftheyhadababy #widow #hawkeye," he said on Instagram.
