Image Credit: Marc Susset-Lacroix/WireImage.comIf you’ve seen director Joe Wright’s last three films — Pride & Prejudice, Atonement, and The SoloistHanna might come as something of a shock. Based on a few minutes of sneak preview footage shown today at NYC’s Comic-Con, the movie has no corsets, no string instruments, and no country mansions. Instead, it’s got guns. And spies. And a deadly teenager (Saoirse Ronan) who was raised as an assassin by her father (Eric Bana) and sent on a mission to find a CIA agent (Cate Blanchett).

In other words, it’s not something you’d expect from a guy whose movies usually appeal to the Masterpiece Theatre demographic. “Everyone thinks I’m all classical music and period films,” Wright tells EW. “It was very exciting to get the gloves off. I really enjoyed all the action stuff. It’s like pure filmmaking.”

For action-movie vet Eric Bana (Star Trek), the thrill of the movie was in the freshness of its story. “When I read the script I felt like I’d never seen that film,” says Bana. “It felt totally original. And that’s getting harder and harder to find, so when you do, you jump on it.”
