Tris V. Dark Tris: Shailene Woodley Takes Us Inside That Crazy 'Insurgent' Fight Scene

Plus, why she feels for Lindsay Lohan.

With reporting by Josh Horowitz

Shailene Woodley knows better than anyone that we can be our own best friends...or worst enemies. As Tris in "The Divergent Series: Insurgent," Woodley had to engage in hand-to-hand combat with herself, a shooting process that she said was almost as difficult as the psychological implications for her character.

"I had so much empathy for Lindsay Lohan in her 'Parent Trap' situation, because filming with yourself, you're not filming with yourself, that's the hard part," Woodley told MTV News.

The technical process of shooting a fight scene with herself -- coordinating the timing and lighting, not to mention the actual acting itself -- was not a simple process. "It was math and logistics and just everything involved was tricky," she said.

"Insurgent," the follow-up to last year's "Divergent," finds Tris at a personal crossroads. After discovering that she's Divergent -- a kind of personality that can't be neatly categorized in her highly regimented society -- and the faction system falls, Tris and her comrades, including boyfriend Four (Theo James) must battle against the villainous Jeanine (Kate Winslet). Of course, there's the little matter of Jeanine believing that Divergents are dangerous and must be tested and studied before ultimately being destroyed.

In trailers for the movie, we've seen Jeanine pitting Tris against a version of herself. Though the movie takes place in a fictionalized post-apocalyptic society, Woodley saw some real-life implications in the fight.

"I think that we're always sort of our toughest opponents, right?" she said. "Because we know the deepest, darkest secrets of our souls and we also know the greatest light of our beings. So when your cluttered self, your dark self, your angered, pessimistic, cynical self comes to surface itself in a physical manifestation, I would think that would be quite terrifying."
