‘Divergent’ foes Shailene Woodley and Miles Teller are off-screen BFFs

Shailene Woodley and Miles Teller may be mortal enemies on screen but their real-life relationship tells a much different tale. Woodley and Teller, who play Tris and Peter in the dystopian blockbuster "Divergent," happen to be best buds off screen.

The duo first met in 2012 before they started filming the indie romance "The Spectacular Now" in Georgia. According to Woodley, even then she found they had "a nice little flow."

In the film, Teller plays Sutter, an alcoholic high school senior who falls for Woodley's down-to-earth bookworm character, Amy. They shot in Athens, Georgia, in July 2012 oand during that time the film's stars became close friends.

"We kind of have a shorthand now," Teller told Vulture earlier this year, explaining, "it’s just very playful."

But "The Spectacular Now" is spectacularly different from "Divergent," the big screen adaptation of the popular trilogy about a dystopian society in which a girl named Tris discovers she does not belong to the five factions within her community. Teller's Peter becomes a member of Tris's chosen faction and systematically bullies her during their entire initiation.

The 27-year-old actor told Forbes last year that he didn't mind playing his friend's worst enemy less than a year after playing her lover.

“It was fun after being in love with Shailene to just be like an a--hole to her,” Teller said. “I had a lot of fun doing that.”

In fact, it was the 22-year-old actress who got him to sign on to "Divergent" in the first place, which started shooting in April 2013. According to Teller, he was initially offered the role of Eric but he didn't think he was quite right for it.

"So then they said, 'What about Peter?'" he told Vulture last year, "And then Shailene shot me a text message saying, 'Please come do this movie with me.'”

As it turns out, Teller and Woodley are equally playful on set.

"Miles is my favorite person to act across from, because we both approach acting from the same vantage point — which is, we really both love to be on a movie set," Woodley told Entertainment Weekly in January. "A lot of actors go on movie sets and take it incredibly seriously, and don’t talk to anyone, and kind of keep to themselves, or have to keep in character. Which is their process, and there’s no judgment, and that’s great for them. But that’s not how I work. I love the interaction with every single person involved, and so does Miles. So it was fun to have somebody that I could play with."

"Divergent" hits theaters on March 21.
