Thanks to M for the heads up.

“I’m sorry, my voice might be a little hoarse,” Saoirse Ronan cautions when she gets on the phone from Los Angeles, where she is doing press for “Hanna.”

The night before, the star of the hard-driving, surprisingly emotional action flick attended the Lady Gaga concert at the Staples Center. This morning, her Irish accent has an even more loamy quality.

“It was amazing. It was absolutely fantastic,” says Ronan.

The concert tickets were a birthday gift from her parents. In a little less than a week, the actress with eight films and one Academy Award nomination to her credit will turn all of 17.

Most actors who come to the big screen as children migrate to adult careers with varying degrees of success. Got it: Anne Hathaway. Figuring it out: Zac Efron. Flailing miserably: Lindsay Lohan.

From the start, Ronan eluded the box. Even at 12, she never seemed to be a “child actor,” just a gifted performer guided by intriguing choices.

“We have seen kids who are great when they’re young, but when they get into their teens, they aren’t that impressive anymore,” she says. “Because it’s a hard thing to do, convince people that you’ve developed and grown up. Because maybe they always want to see you as an 8-year- old. I’ve never considered myself a child actor.”
