Shailene Woodley will reprise her role as Beatrice “Tris” prior in the upcoming movie “Insurgent.” The film, which is a sequel to last year’s adaptation of the young adult novel “Divergent,” by Veronica Roth, stars the actress as a well-trained soldier in a dystopian future, a role that she now reveals was more difficult to play than she thought.

Filming the movie required a physicality that the “Fault in our Stars” star wasn’t used to as the 23-year-old actress had played significantly tamer roles in the past before signing on to play Tris. In the movies, her character is a “Divergent,” someone that doesn't fit in to her dystopian societies various factions. As a result, “Divergent” saw her and her boyfriend Four (Theo James) in a mad dash to discover what makes divergents so dangerous to society before the villain, Erudite leader Jeanine Matthews (Kate Winslet), attempted to destroy them all.

"[In] the first movie, we did a lot of choreography and fight training, and this one was basic sort of fitness – there wasn’t anything too intense," Woodley told People Magazine, describing an action sequence that required the use of wires. “I was like, 'If I don’t grab this pole, I’m not going to get hurt, but I’m going to be dangling in the air and probably get a really bad wedgie,' so that was pretty fun.”

According to the "Insurgent" first trailer, Matthews finally gets her wish to capture and experiment on divergents in the second movie. She gets a hold of Tris and tries to use her to open a mysterious box that she believes holds the secret to the future that her people “deserve.” Meanwhile, Tris, Four and Caleb (Ansel Elgort) take the fight directly to her with the help of “The Factionless,” a group that is, obviously, without a faction.

“Tris and Jeanine’s relationship has become a power game,” Winslet said of the sequel in an interview to reveal the cast photos. “Jeanine has a very bizarre and uncomfortable fascination with and admiration for Tris.”

The plot of the movie will force Woodley’s character directly into the lion’s den – meaning she’d need to rely on that new physicality in order to make her character’s daring escape believable. Speaking to MTV News, the actress described how difficult a task this proved to be, especially while filming a scene where she was forced to fight a mirror image of herself.

“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 said.

Fans hoping to see if Woodley could pull off the on-screen battle will only have to wait until Friday, March 20 when the highly-anticipated sequel hits theaters.
