'Batman v Superman': Amy Adams on Playing Lois Lane, Shirtless Scenes With Henry Cavill

Amy Adams says she loves playing Lois Lane on the big screen because the character is something she is not: fearless.

"I love that she’s fearless," Adams said today on "Good Morning America." "I’m not that way so it’s really fun that she really is not afraid of the consequences."

Adams reprises her role as Lane in the new "Batman v Superman: Dawn of Justice" movie, out in theaters today. The movie reunites Adams with Henry Cavill, who plays Superman and his alter ego, Clark Kent, in the film.

"What’s great about this is that, as far as the relationship with Lois and Clark goes, when we meet them you can tell that they’ve been in a relationship for while," Adams said. "So it was great to get to develop that sort of intimacy and that sort of friendship that I’ve developed with Henry, to get to bring that to screen."

Cavill is shirtless in some of the film, which Adams revealed had a surprising effect on her during filming.

"I don’t know why him shirtless makes me have low self-esteem but that’s exactly what it did," Adams said. "It was like two weeks of working out."

She added: "I was like, ‘Wait. I’m never going to keep up with Henry.’ But I tried."
