Fans of the Maze Runner series should expect to see a slightly different adventure when they enter theaters for The Scorch Trials.

The second installment of the Maze Runner trilogy will hit theaters in September, and foreboding interviews may have some fans wondering if Fox will actually do the James Dashner novels justice on the big screen. Now that the first trailer is out (see video below), actor Dylan O'Brien's (Thomas) admission that the script 'strayed a little from the book' appears to be more than 'a little' true.

Focusing almost entirely on the transition from the Glade to the Scorch, the trailer shows that the film will abandon the scenes at the alleged safe house, the explanation of the Phase 2, and the Rat Man for a faster-paced more cloak and danger approach that takes place facility much like the WICKED facility Thomas and Co. emerged into at the end of the 2014 film. Instead of being sent into the Scorch, the few survivors will run there on their own.

Dashner, however, is still looped into the entire process.

"James [Dashner] is very involved in the choices that we've been making adapting his book. And our approach has basically been to, you know, take the rest of his stories, the next two books, [Scorch Trials and the Death Cure], that he's created and we're making two movies out of that," director Wes Ball explained in a MTV behind-the-scenes featurette. "Rather than just a straight adaptation out of the second book, we need to start kind of laying a nice liner arch for these characters for the rest of the saga."
