'Divergent' Set First Look: Shailene Woodley Wields A Rifle!

'Her decisions are constantly being torn between whether to be brave or whether to be selfless,' actress says of character Tris in behind-the-scenes footage.

Fans of the Veronica Roth-penned dystopian drama "Divergent" will have to wait until Comic-Con to get their first glimpse at official footage from the upcoming film adaptation, but in the meantime, "Entertainment Tonight" has a behind-the-scenes look at the Chicago set with star Shailene Woodley.

"Her decisions are constantly being torn between whether to be brave or whether to be selfless," Woodley explained of her character, Beatrice "Tris" Prior.

These conflicting allegiances are a key component of Tris' journey of self-discovery. "Divergent" takes place in the near future, in a society that is divided into five factions, each reflecting a different core value: Abnegation (selflessness), Erudite (intelligence), Dauntless (bravery), Amity (peacefulness) and Candor (honesty). As a teen, each citizen takes an aptitude test that helps determine which faction they will choose to align with. When Tris, raised in an Abnegation household, earns an inconclusive score, she decides to break from her family and join up with the daring Dauntless (hence the rifle we see Woodley wielding in the "ET" footage).

"Divergent" is one of several YA novels making the leap to the big-screen this year, and according to co-star Zoe Kravitz, who plays fellow Dauntless initiate Christina, this adaptation is one to watch.

"I think we're going to kill it," she enthused.

Of course, a nice promotional push from studio Summit Entertainment, including the aforementioned appearance at Comic-Con, won't hurt. The cast, including Woodley, Theo James, Miles Teller, Maggie Q, Ansel Elgort, Mekhi Phifer, Ben Lamb, Ben Lloyd-Hughes and Christian Madsen, in addition to director Neil Burger and author Roth, will answer questions and debut footage during a Hall H Panel on Thursday, July 18. And you'll want to stick close to MTV News throughout the Con, as we'll be live-streaming the best and brightest beginning July 17.

"Divergent" hits theaters March 21, 2014.
