Those who have read the book know where it goes. It goes into a whole different world, and we're really excited to explore that."

"CL Casting is looking for a ton of actors, models, and talent to work on the upcoming Divergent Series sequel," Project Casting said. "Filming will take place in the Atlanta, Georgia area. Currently, casting directors are looking for athletes, police officers, fit people, and people with visible muscles. Those that are selected will go to a bootcamp and tactical training for the upcoming feature film."

Shailene Woodley and Theo James will reprise their roles as Tris and Four, respectively, on "Allegiant Part 1." The film is directed by Robert Schwentke and scheduled to be released on March 18, 2016.
