Is Saoirse Ronan Nude In “How I Live Now”?

"How I Live Now" is one part coming of age story and one part dystopian nightmare. Saoirse Ronan stars as Daisy, an American girl caught up in the fallout of an increasingly militarized UK. And at some point--we're not clear on how the plot gets us there--Saoirse's character goes running naked through the woods. But is it actually Saoirse, or just a body double?

We'd like to believe it's her, but something about the scene makes us think it's a body double. That said, we hear there's a sex scene in the film as well--so we'll definitely be on the look out for that one.
