Chris Evans is a man of many talents, but few knew he grew up with a spring in his step.

"I tap dance," the actor, 30, reveals in a behind-the-scenes video for his May 2012 Details cover shoot. "My mother was a tap dancer, and as a result, we all grew up with an understanding of tap dancing."

The Avengers star crafted his skills in the theater, playing Snoopy in his school's production of You're a Good Man, Charlie Brown. "It was a great play. It's got a lot of good songs," Evans says. "It's part of my childhood."

Evans also tells Details how he blew his audition for Gone Baby Gone thanks to an awkward encounter with Ben Affleck.

"I've never told this story on camera, but it's funny," Evans laughs. "I parked my car and I walked into this building, and I heard somebody say, 'There he is!' It was Ben, and immediately -- I don't know why -- I was nervous. I walked in the room, shook his hand and I said, 'Hey, nice to meet you. Am I going to be okay where I parked?' And he said, 'Where'd you park?' And I said, 'At the meter.'"

Without missing a beat, an amused Affleck said, "'Did you put money in the meter?'" Evans recalls. "I said, 'Yeah,' and he said, 'I think you're going to be okay!'"
