With the success of "The Maze Runner" film, this has put the entire cast and the book-to-film adaptation at No. 1. They are five items that could put the next "Maze Runner" ahead of its pack, one of them includes a star from the "Divergent" sequel "Insurgent."

The film received great reviews and even better box office receipts. Here are five things that could put "The Maze Runner" sequel at No. 1 again.

"American Horror Story" alum Rosa Salazar has signed onto the sequel. Salazar is expected to play the role of Brenda who is a significant character in the book series, IGN reported.

Salazar is no stranger to young adult and dystopian films. She has already completed a small role in the "Divergent" sequel "Insurgent," The Hollywood Reporter confirmed. Besides appearing in "American Horror Story," Salazar has also appeared in NBC's "Parenthood."

"The Maze Runner" star Dylan O'Brien, at the moment, will be back playing the thrust on leader Thomas. In the sequel, both characters -- Salazar's Brenda and O'Brien's Thomas -- will be teaming up and are expected to be running around in a set of underground tunnels, IGN reported.

A "Game of Thrones" star will also be in "The Scorch Trials." Aidan Gillen, who played Petyr "Littlefinger" Baelish in the HBO series, has joined the cast as the film's villain, IGN reported. The previous director Wes Ball, along with the producers, will also be returning.

In the previous "The Maze Runner," based on James Dashner's book, audiences saw that the film was set in a post-apocalyptic world. O'Brien's Thomas wakes up in this world and finds himself within a community of children. These children then welcome him to the "Glade" -- this a large piece of land that is completely surrounded by a concrete maze, IGN reported.

In "The Maze Runner Chapter II: The Scorch Trials," Thomas will meet Brenda. Thomas and Brendas' teams will come together to face Wicked's Phase 2 of their trials, MoviePilot reported.

"The Maze Runner" opened with almost $35 million amidst a film season that is considered to be a slump. The critics and audiences loved it. The film's success was so huge that Twentieth Century Fox, the movie's distributor and copyright holder, green-lit a sequel soon after the box office receipts came in.

The writer Dashner -- whose books the films are based on -- has a say about "The Maze Runner" book series. At the moment, there are four books in the "Maze Runner" series: "Book 1: The Maze Runner," "Book 2: The Scorch Trials" and "Book 3: The Death Cure." The fourth book in the series, "Prequel: The Kill Order," takes place at the beginning, when there was no maze and before any of the characters emerged.

But Dashner has not escaped the maze. He is now working on a fifth book titled "The Fever Code," and it is scheduled to come out in 2016. This new story will focus on the time just before the maze was built. And it will tell the story of how Thomas, Teresa and the Gladers found themselves in the Maze.

"From the very beginning, I've always wanted to write a prequel about Thomas, Teresa, Newt, Minho, Alby and all the Gladers that leads up to the very moment Thomas enters the Box," Dashner said, USA Today reported.

Finally, when is "The Maze Runner Chapter II: The Scorch Trials" expected to come out? With Fox studios' immediate green-light on the project, the sequel is expected to debut on Sep. 18, 2015.
