Dylan O'Brien shouldn't have been Thomas.
When the casting process for the first film started, director Wes Ball took one look at the kid and said no. Why? His hair. Specifically, his "Teen Wolf hair." Ball thought O'Brien looked like a "badass action star" already, and he wanted someone who felt vulnerable—a boy who would eventually grow into a man. It took a random photo of Dylan with a buzz cut for the director to realize he’d missed the perfect lead.
That little piece of trivia is basically the foundation of the whole franchise. Dylan O'Brien The Maze Runner isn't just a movie series; it's a saga of survival that almost ended in real-world tragedy.
The Casting Gamble That Paid Off
Most people forget that back in 2014, the "Young Adult Dystopian" genre was crowded. The Hunger Games was the king, and Divergent was trying to take the throne. The Maze Runner felt different because it was grittier and, honestly, a bit more claustrophobic.

Dylan brought a weird, frantic energy to Thomas. He wasn't the "chosen one" who knew everything. He was just a guy who woke up in a box and refused to stop asking questions. That curiosity is what makes the first film stick. While the book version of Thomas had a telepathic connection with Teresa (played by Kaya Scodelario), the movie ditched that. It was a smart move. It made the isolation feel real.
The chemistry between the cast wasn't just for the cameras, either. Dylan, Thomas Brodie-Sangster (Newt), and Ki Hong Lee (Minho) became actual best friends. Fans still call the Dylan and Thomas duo "Dylmas," and if you look at any press tour footage from 2014 to 2018, you’ll see they spent half the time just making each other laugh. That bond is why the ending of The Death Cure hits so hard. You aren't just watching characters; you're watching friends.
The Accident That Changed Everything
We have to talk about what happened in March 2016. It’s the elephant in the room whenever anyone brings up the trilogy.

While filming a stunt for The Death Cure in Vancouver, things went horribly wrong. Dylan was reportedly pulled from the top of one moving vehicle and struck by another. The injuries were devastating: a concussion, facial fractures, and brain trauma. Production didn't just pause; it shut down for an entire year.
There was a long time where nobody knew if Dylan would ever act again. He’s been open about the "dark place" he went into during recovery. He had to undergo reconstructive surgery on his face. Honestly, it’s a miracle he came back to finish the film at all.
When he finally did return to the set of Dylan O'Brien The Maze Runner: The Death Cure, he was a different person. He has mentioned in recent interviews, like with Men's Health, that the accident taught him to stand his ground. He had raised safety concerns that day, and they weren't listened to. Now? He’s the first one to speak up on a set.
Why the Trilogy Still Holds Up in 2026
Looking back, the movies are surprisingly solid.
The first film had a tiny budget of $34 million. That’s peanuts for a sci-fi blockbuster. Yet, it grossed over $348 million. The "Grievers"—those mechanical spider-monsters—still look terrifying because they used a mix of practical sets and smart CGI.
- The Glade: They actually built a lot of that set in Louisiana. The sweat on the actors? Mostly real. The humidity was brutal.
- The Stunts: Dylan did a massive amount of his own running. He’s naturally athletic, which helped, but the sheer volume of sprinting in those movies is exhausting just to watch.
- The Stakes: Unlike other YA series that got bogged down in romance, The Maze Runner stayed focused on the "WCKD is Good" moral gray area.
The series ended on its own terms. They didn't split the final book into two parts like Twilight or The Hunger Games did. They just told the story and got out. That’s rare.
What You Should Know Before a Rewatch
If you’re planning to dive back into the Scorch or the Glade, keep an eye on the details. The movies deviate a lot from James Dashner’s books. In the books, the characters are all infected with the Flare from the start. In the movies, they’re mostly immune. This changes the motivation of the villains significantly.

Also, look at the growth in Dylan’s performance. In the first film, he’s wide-eyed and twitchy. By The Death Cure, there’s a heaviness in his eyes that wasn't there before—partially because of the character’s journey, and partially because of what the actor went through in real life.
Actionable Takeaways for Fans
If you're inspired by Dylan's journey through this franchise, here’s how to channel that:
- Watch the "Ruin" Short Film: This is the 3D animated short Wes Ball made that got him the job. You can see the DNA of the Maze in every frame.
- Advocate for Yourself: Take a page out of Dylan’s post-accident playbook. If something feels unsafe or "off" in your workspace, speak up. Being "difficult" is often just a label people use to ignore valid concerns.
- Support the "Middle-Budget" Movie: The Maze Runner proved you don't need $200 million to make a good sci-fi flick. Look for smaller indie projects the cast has done since, like Love and Monsters or Caddo Lake.
The legacy of Dylan O'Brien The Maze Runner isn't just the $949 million it made at the box office. It's the story of an actor who survived the literal and metaphorical maze of Hollywood and came out the other side with his integrity intact.
For your next move, check out Dylan's work in Saturday Night (2024) to see how much his range has expanded since his days running from Grievers. Or, if you're feeling nostalgic, go back and watch the first Maze Runner and look for the scene where Thomas first enters the Maze—the look on Dylan's face is pure, unscripted adrenaline.
