The second movie will see the return of Shailene Woodley and Theo James as the main heroine and her love interest respectively. Other returning members include Miles Teller, Ansel Elgort, Kate Winslet, Jai Courtney, and Zoe Kravitz.
Based on Veronica Roth's novel of the same title, the first film directed by Neil Burger bagged $266 million worldwide. The follow-up is helmed by Robert Schwentke with script by Brian Duffield and Akiva Goldsman. Octavia Spencer is also among the new additions.
