Saoirse Ronan: Wonder Woman at WonderCon!

Saoirse Ronan shows off her pearly whites as she attends 2011 WonderCon at Moscone Convention Center on Saturday (April 2) in San Francisco.

The 17-year-old Irish actress, wearing a Junk Food Clothing tee, was there to promote her new film, Hanna, with director Joe Wright.

Joe told the LA Times that it was really Saoirse that hired him for the movie. “If Saoirse hadn’t been involved I wouldn’t have given it much attention. But because she was, I thought I should take it seriously. Saoirse hired me.”

“They said they didn’t have a director. So I said, ‘Why don’t you just ask Joe Wright to do it?’” Saoirse admits.

Saoirse also wore Caleo “Pinch” earrings and Robert Clergerie flats.
