Eyes up here, Captain America! Chris Evans couldn’t keep his eyes off one (or two) of his Captain America: Civil War co-stars at the London premiere of the action flick on Tuesday night.

Evans was photographed staring at Elizabeth Olsen’s exposed cleavage, seemingly mesmerized. Olsen, who plays witch Wanda Maximoff in the Avengers films, wore a stunning white gown with a plunging neckline.

Though the photos say otherwise, Evans recently opened up on Anna Faris’ podcast about his favorite female body part.

"I'm way, way, way more of an a** man, clearly more of an a** man,” he declared at the time. “Just everyone knows. I like butts."

The Marvel super heroes are preparing for their next installment, Civil War, which will hit theaters on May 6. Evans recently told ET’s Carly Steel that he gave the film his all, and maybe went a little too hard during filming.

“I actually messed up my arm doing it, I really did," Evans told ET of a sexy shot of him holding onto a helicopter. "It's a fake helicopter, obviously, but it was drifting beyond the ability of control. I tweaked a little something. To this day, I'm still messed up."
