Shailene and Theo risk their lives for Insurgent!

If the awesome fight scenes and epic zip line sequence in Divergent gave you chills, get ready for your stomach to do full on somersaults during Insurgent. The anticipated sequel has been filming in Atlanta, Georgia, and sets were created on the rooftops of several buildings, which were connected by zip lines. Whoa! This can only mean lots more action for stars Shailene Woodley and Theo James. But don't worry, stunt men and women were spotted testing the zip lines for safety before Shailene and Theo filmed. Doing the stunts was one of Shai's favorite parts of making the first movie. "The stunts were fun, the fighting sequences were really neat," she spills. We can't wait to see how Shai and Theo crank up the action onscreen in Insurgent.
