makeup made his daughter cry.
The 39-year-old actor - who has 13-month-old James with his wife Blake Lively - admits the Gossip Girl actress was "blown away" by the costume he wore for the superhero film but the scar makeup didn't go down too well with his little girl.
He said: "[Blake] was blown away by how much the suit was such a faithful adaption from comic book to screen ... probably the most faithful adaptation that's ever been done.
"And my daughter would cry when she saw me in the scar makeup. It was hard. She would hear my voice, but she'd see this guy that looks like a fried testicle. That's tough for a kid."
And despite the Super Bowl 50 being right around the corner and Ryan himself currently in California, where the game is taking place Sunday, he is eager to get back to be with his family.
He told Entertainment Tonight: "I've got a 1-year-old at home and a wife waiting for me, and I'm going to get out of here tomorrow before the zoo happens and watch on TV.
"It's hard explaining to your wife that you're hanging out at the Super Bowl when she's stuck at home with the baby: 'Yeah I'm just gonna stay for the game or maybe stay for an extra couple of days or nights.' No! You go home."
