Divergent: Allegiant is underway and the franchise' frontrunners Shailene Woodley and Theo James revealed how much they admire their characters' relationship.  James said that Woodley's personality makes everything easier during filming. Meanwhile, Woodley's former co-actor Allen Evangelista also revealed Woodley's 'other personality' behind the cameras.

Theo James and Shailene Woodley revealed in an interview that they both like how Four and Tris support each other in their relationship, "People love that they support one another so much and respect one another. It's sexier to see a couple that aren't all over each other," Woodley said. While James said that Four and Tris were two people in love, but "broken by the situation they're in." He further described their story as, "They go from a burgeoning love story to two people genuinely in love," he said.

Meanwhile, James and Woodley's friendship seem to be going strong as James also revealed that aside from their friendship, Woodley's attitude and personality makes filming critical scenes as well as intimate scenes much easier.

He also added that even behind the scenes, Woodley's personality continue to glow, "She's probably a much better person than I am. I was impressed by her level of ethical ability to kind of strive to be a better person-like with her environmental issues...Shai is 100 percent genuine in her way and very real. She really does those things in a way that puts us all to shame" he said.

Woodley's former co-star in the series "The Secret Life of the American Teenager", Allen Evangelista, revealed Woodley's attitude when the cameras weren't rolling in front of her.

"She's always been really nice and sweet and she gives cast gifts at the end of every season and writes us letters and then we'd all talk and hang out. She's very, very sweet and humble and down-to-earth," Evangelista said.  

He also praised the actress for recent works, especially her performance in the movie, "The Fault in Our Stars" which she co-starred alongside Ansel Elgort.

Divergent: Allegiant Part 1 stars Shailene Woodley, Theo James, Ansel Elgort, Zoe Kravitz, Naomi Watts, and many others. It is directed by Robert Schwentke, and is set to hit theaters in March 18, 2016.
