The production had to hire snake wranglers to make sure the areas where they were filming were snake free. Before filming began the wranglers found 25 venomous snakes. The biggest one they found was a 5 foot rattlesnake.
To gain the role of Chuck, actor Blake Cooper continuously campaigned for an audition via twitter. He would send director Wes Ball tweet after tweet after tweet stating that he was made for the role. Wes Ball eventually relented and told Cooper to send his audition to the casting director who stated that Cooper was the perfect Chuck.
The cast spent the week before production participating in survival training in the glade. They learned how to build tools and shelter out of the surrounding nature.
Of the largely British cast, only actor Thomas Brodie-Sangster, who plays Newt, got to keep his accent.
Many of the characters' names are taken from historical figures and most are from inventors, mathematicians, philosophers, or scientists to illustrate their intelligence (which was a major plot element in the novel): Thomas (Thomas Edison), Alby (Albert Einstein), Newt (Isaac Newton), Chuck (Charles Darwin), Gally (Galileo), Teresa (Mother Teresa), Winston (Winston Churchill), Ben (Benjamin Franklin) and Frypan, in the novel also called Siggy (Sigmund Freud). Author James Dashner has said that Minho is not named after anyone famous but his niece's Korean husband. The novel also featured other characters such as Aris (Aristotle) and Harriet (Harriet Tubman).
In the book, Teresa and Thomas could communicate by speaking in each other's minds.
Dylan O'Brien's hairstyle almost cost him the role of Thomas, because director Wes Ball thought it was too "MTV". Ball reconsidered when he was sent a photo of O'Brien without his hair gelled.
To prepare for shooting, director Wes Ball had the cast spend a night in the Glade set during boot camp.
Producer Wyck Godfrey had his 3 boys offer casting advice. He would show his kids the auditions and get their feedback. His kids have read the books.

Dylan O'Brien's character in Teen Wolf was unconscious for most of the episode "Lunar Eclipse" in order for him to finish filming The Maze Runner.
Director, Wes Ball originally pitched 'The Maze Runner' as "Lord of the Flies meets Lost".
In the book, the walls of the maze were much, much taller which is why the gladers weren't able to climb them to the top. The maze is also contained within a dome. The sky and the weather are all artificial.
Kaya Scodelario's favorite day on set was when she spent an entire shooting day on the top of a tree with O'Brien. She said that was when they really spent time together as actors and got to know each other better.
Dylan O'Brien's favorite scene to shoot was the wrestling sequence with Will Poulter.
Dylan O Bryan actually broke his cheekbone while filming The Maze Runner. It was the scene where he was running from his first griever and when he went to jump, he slipped.
The filmmakers never tested the cast members' physical abilities (i.e. making them run or jump) before the shoot.
Having seen her work on the UK series Skins (2007), Ball wanted Kaya Scodelario to play Teresa from the beginning.
Changes from the book to the movie include downplaying telepathy between Teresa and Thomas, and downplaying Teresa's coma.
Thomas Brodie-Sangster auditioned for both Thomas and Newt. Will Poulter auditioned for Gally and Newt.
In the movie the grievers have legs and run, but in the book they roll and have arms inside them that come out and have things such as knives on the end.
Director, Wes Ball originally met with Fox Studios to direct a feature length version of his short film 'Ruin'. They offered him the chance to direct 'The Maze Runner' and he accepted.
In the books, the Gladers all know their names when they first come up. It doesn't take a few days to come to them.
In the scene where Thomas first writes his name of the wall with the other names there is the name "Alec" which is a reference to the other maze runner series book kill order where Alec is one of the main protagonists
The book features the "Glader's" own slang, including shank, shuck, klunk, greenie, slinthead, shuck-face, and a few others. The movie also has a few here and there. Will Poulter (Gally) and Ki Hong Lee (Minho) revealed their favorites; Will's being shank and Ki Hong's being shuck.
Brenton Thwaites and Connor Paolo auditioned for the role of Thomas, but lost to Dylan O'Brien.
Ball mentions Jurassic Park (1993) as one of the films that has most influenced his style, as he wants to make a PG-13 movie that doesn't pander to kids.
In the book the Gladers don't throw in curse words every now and again but use their own like shuck.
The first 20th Century Fox film to be an all-digital release, with no 35mm prints made.
Director Wes Ball watched a lot of Terrence Malick for inspiration as he liked the idea of a mature, sophisticated look to the movie.
Thomas Brodie-Sangster's favorite scene to film was the scene where he and Thomas (Dylan O'Brien) are sitting by the log and talking about the maze because he said that it wasn't a big scene, it was relaxed
Wes Ball worked with a concept artist in Belgium to create the concept artwork for the film. Wes has never met him or spoke to him aside from in emails and IMs.
The first scene of Scodelario's character arriving in the middle of the Glade surrounded by 30 boys is the very first scene she shot.
The production filmed over 18 acres of land on a local farm. The farm has 200 acres.
Many of the slang words used by the Gladers first appeared in a sketch on The Ronnie Johns Half Hour (2005), in which a member of the Australian Classification Board gives a lengthy list of acceptable substitutes for the word "dickhead".
The crew got 36 setups done on the first day of shooting. One day they were rained out and lost 6 hours but still got 39 setups. Sometimes they are shooting with three cameras at the same time.
In the book, Thomas sees the body of the Glader who tried to escape from the Box hole at the cemetery in the woods, where Ben attacked him and Alby shot an arrow at Ben.
In the book, Teresa spent some time in the pit, whereas it doesn't happen in the movie.
In the book, Gally had snuck out of the maze and gotten stung, while in the movie he didn't.
When Thomas (Dylan O'Brien) is carving his name on the wall, the name "Scott" can be seen. In Teen Wolf, the best friend of Dylan O'Brien's character Stiles Stilinski, is named Scott.
Both Ki Hong Lee (Minho) and Dexter Darden (Frypan) have starred in season 1 of the Nickelodeon show Victorious (2010).
