Last week, MTV News revealed that the third movie in "The Divergent Series" would be getting a new name: "Allegiant." And now, the doors that separate the ruins of Chicago from the rest of the world are opening even further, with our exclusive first look at the set of the film.

The movie won't open until March 18, 2016, but earlier this year, Tris (Shailene Woodley), Caleb (Ansel Elgort), Peter (Miles Teller) and more welcomed MTV News on set to discuss the important issues. Like, what's up with Tris, now that she knows Divergents -- people born with more than one personality trait, an ability most of their post-apocalyptic society don't posses -- are harbingers of their escape from Chicago? And more pressingly, what's up with Tris' hair this time around?

"The first movie was about Tris sort of following Four [Theo James]," Woodley told MTV News. "The second movie, Four was sort of following Tris to stop her from following her impulsive nature. And in this movie, we thought it would be lovely to create a balance of the two."

To find out more about "Allegiant" -- including greeting new cast member Jeff Daniels, who plays a key role in the film -- as well as whether Elgort or Teller think they have the best hair, watch the first look above!
