"The Divergent Series: Allegiant" will feature younger versions of Four and Natalie Prior.
According to Design & Trend, the producers of the movie recently cast two actors to make a cameo in the film.
"This is going to be the first time in the series that the audience will see Four as a child. We will be seeing Natalie Prior as a young girl in this movie," the film's IMDb page read.
Meanwhile, cast members Shailene Woodley and Theo James are reportedly excited to work with their new cast members.
Although James wouldn't have a scene with his character's younger version, there were previous reports that claimed both he and Woodley were friendly to everyone on set.
As of late, it is still unclear what scenes that two young characters will star in.
In other news, Woodley and James recently revealed how close they have become on the set of the three films.
During an interview, James even joked about sleeping with Woodley on the same bed.
The actor immediately clarified that there is no truth to what he said. What really happened was that all of the cast members lived close to each other.
"We all hung out a lot. It was fun. We were all in this one apartment. We're all sharing a bed - me and Shailene just shared a single bed and were just like spooning every night!" he said.
In a separate interview, James revealed that didn't have any problems filming intimate scenes with Woodley.
"I just went at it hard, to be honest, because I thought that's how she wanted it... I just wanted to practice the kissing scene with Shai as much as possible. I'd say, 'Listen, after dinner we could just go over that scene again...'" he said.
"The Divergent Series: Allegiant" is slated to hit theaters in the United States on Mar. 18, 2016.
