James Dashner reviewed the Maze Runner trailer and shared his thoughts with an entertainment website. Read on to see his commentary frame by frame.

As reported earlier, the official Maze Runner trailer premiered last night during a new episode of MTV’s Teen Wolf. This morning Entertainment Weekly caught up with James Dashner, the author of the original book series the movie is based on, to have him share his thoughts on the newly released trailer.

Watch the trailer bellow to follow along with his comments:

Dashner starts by talking about how the opening scene of the book was adapted to fit the context of a movie. He said, “I think Wes Ball captured the spirit of that pivotal opening moment so perfectly, showing the terror in Thomas’s eyes and the dirt and sweat and jerky movements of it all. The sounds are so perfect, cranking and squealing and metallic jolts. I got chills when the doors opened.”

The best selling author goes on to say that the visual of Gally jumping into the Box was one of his favorite images to see and praises Will Poulter for his performance as Gally. He spoke about how Aml Ameen makes Alby into such a calming, powerful leader, and says that “People are going to go nuts when they hear Newt (Thomas Brodie-Sangster) speak for the first time.”

“Dylan O’Brien can act, just with his facial expressions and body movements alone. This guy is a star, period.”

Dashner didn’t spare any kind words for Dylan O’Brien or his portrayal of Thomas either. He said to EW, “I saw so much footage throughout the process without sound, and something that always struck me was how well Dylan O’Brien can act, just with his facial expressions and body movements alone. This guy is a star, period.”

He also highlighted a few things created for the movie adaptation, such as the added treehouse/lookout structure and the way the Gladers have carved their names into one of the interior walls of the maze. These new elements seem to please Dashner and his enthusiasm for Wes Ball’s vision comes through during his review of the trailer.

He closed the article by sharing his thoughts on the ending title sequence, “I don’t even know what to say about it. So perfect. When I saw the trailer for the very first time, at this point I just started bawling, so many emotions exploding at once. To see my world come to life, so stunningly and so professionally, and to love it so much, just overwhelmed me.”
