Saoirse Ronan Talks 'How I Live Now'

Saoirse Ronan heads to the theaters at the Grove with a friend in Los Angeles on Friday afternoon (September 13).

The 19-year-old actress just arrived from premiering her new film, How I Live Now, at the 2013 Toronto International Film Festival.

“I actually wasn’t nervous about it,” Saoirse shared with MTV about the intimate scene in the film. “It was always written in the script, and there needed to be a sex scene in this film.”

She continued, “They needed to consummate their love, I think, in order for us to really feel the heartbreak when they’re separated because obviously, it becomes a lot more intense after.”
