Shailene Woodley and Theo James are set to reprise their roles as Tris and Four in the upcoming sequel "Insurgent" to be released in 2015.

After the huge success of the movie "Divergent," the highly anticipated second installment is on its way.

The sequel entitled "Insurgent" is set to be released on March 20, 2015, after filming ended last June.

Divergent stars Shailene Woodley and Theo James will reprise their roles as Beatrice and Four, respectively, in this second part of the movie series.

In an article by Fashion & Style, it shared that dangerous stunts can be expected from the movie. Some sets are built on top of several rooftops connected by zip lines. This included one on top of the Peachtree Center in Atlanta. Some stunt people were filmed while testing the zip lines.

Fans can expect to see a lot of sneak peaks of the upcoming sequel in the "Divergent" DVD. It will be released on August 8 this year. Some behind-the-scene clips are also included in the DVD.

One of the BTS clips is the creation of Four's tattoos on his back and a fighting scene with Tris. According to an article in Fashion & Style, it was a great task to apply the tattoos to James' back. According to James, it was also very painful, but he does not complain.

The movie is being directed by Robert Schwentke and writhed by Brian Duffield and Akiva Goldsman. Other casts include Ansel Elgort as Caleb, Miles Teller as Peter, Kate Winslet as Jeanine, Hai Courtnety as Eric, Naomi Watts as Evelyn, and Zoe Kravitz as Christina. Recently, Keiynan Lonsdale was casted as Uriah.

Meanwhile, author Veronica Roth has released a book entitled "Four: A Divergent Collection" last July 8. The book focuses on Four and gives a more detailed background on his life before meeting Tris.

The movies are based on the 3-part series written by Veronica Roth and published by Harper Collin in 2011.
