“The Maze Runner” star Dylan O’Brien wants fans to be prepared for the film series to diverge further from the books in the upcoming sequel, “Maze Runner: The Scorch Trials.”“We strayed a little from the book, so I hope [the fans] are cool with that because we still have plenty of stuff from the book in there,” O’Brien says to Zap2it before the “Teen Wolf” panel at Paleyfest 2015.While O’Brien wasn’t specific about what changes were made from the book to the film, he did say that he feels good about what they were able to capture and he delivered his best for fans of the book series and the first film.“I walked away every day proud,” he says. “That’s all I can worry about. I can’t worry if the movie is good too.”The second book in James Dashner young adult series picks up after Thomas (O’Brien) and his friends have escaped from their prison maze called “The Glade.” Now they must make their way through their disease-ravaged world to figure out why they’re being experimented on and to have a chance at surviving The Flare — a deadly virus that slowly erodes one’s humanity.The first movie, “The Maze Runner,” also diverged from the source material, notably by playing down the romance between Thomas and Theresa (Kaya Scodelario) to focus on their attempts to get out of the maze. In “The Scorch Trials” Thomas meets another potential love interest in Brenda (Rosa Salazaar) though, so the film series has some catching up to do if they plan to stay true to the series’ love triangle.The film wrapped production in January and is still in the early stages of editing, so O’Brien can’t weigh in on the final cut yet.“We just wrapped shooting a month ago. They’ve only been cutting it for that long, so I haven’t seen it. I think it’s great though,” O’Brien says. “I feel like we accomplished something every day. I just have to be happy with the experience, and I am, so that’s the icing on the cake.”“The Scorch Trials” hits theaters on Sept. 18.
