'Captain America' Star Chris Evans Jokes With Young Fan About Arm Wrestling Dad

"Captain America: Civil War" opens nationwide tomorrow.

“It’s the first time he doesn’t know what’s quite right or wrong,” Evans told Amy Robach. “He’s a very binary thinker and I think in the previous incarnations it’s clear to understand…aliens invading are bad -- this is the first time he’s not quite sure which side of the fence to fall on.”

“Seeing friends fight friends is a little more dynamic than seeing a friend fight an enemy,” Evans said.

In Times Square this morning, Evans was interviewed by pint-sized fans that proudly wore their Captain America gear in support of their favorite superhero.

“My dad’s on ‘Team Iron Man’ and I’m on ‘Team Cap.’ What do you think I can do to make him be on ‘Team Cap?’” asked little Camilla.

Evans responded: “Your dad’s on ‘Team Iron Man?’ Is he a big man? Because I would say I’ll arm wrestle him – and then we’ll squash it once and for all, but if he’s like 6-foot plus I’d say maybe let’s talk it out.”
