How Old Was Dylan O'Brien in Maze Runner 3
Dylan O'Brien was 25 years old at the time of Maze Runner: The Death Cure's primary filming in 2016. He was born August 26, 1991, and principal photography ran from February to July 2016, making him 24 turning 25 during production. The film released in January 2018, by which point he was 26. His age aligns with the late-teen post-apocalyptic setting, as the characters are intended to be young adults navigating the maze and WCKD experiments.
Key Filming Dates and Age Timeline
Understanding the production schedule helps clarify age questions, because The Death Cure was not filmed all at once but in multiple blocks with breaks. Casting announcements, script revisions, and physical recovery influenced when cameras rolled. Here is how the timeline aligns with Dylan O'Brien's age.
Preproduction and Casting (2014–2015)
Development for The Death Cure moved slowly after the second film, with casting and script details confirmed in 2015. Dylan O'Brien was already established as the lead and his age remained consistent with the character description throughout this period.
Principal Photography (2016)
Main photography began in February 2016 and concluded in July 2016. Dylan O'Brien turned 25 in August 1991, making him 24 during much of the shoot and 25 by the later months. This is the core answer to how old he was in Maze Runner 3.
Postproduction and Release (2016–2018)
Editing and visual effects work extended into 2017, with the film finally opening in theaters in January 2018. Dylan O'Brien turned 26 in the calendar year of release, but his onscreen age reflects the timeline of the story rather than the release date.

Context Around Maze Runner 3's Production Timeline
The Death Cure had a prolonged development and filming timeline compared with the first two movies. Dylan O'Brien sustained a serious on-set accident in 2016, which caused delays and influenced the shooting schedule. His recovery, script adjustments, and VFX work extended the overall production window, which can create confusion about his age during different phases of the project.
Cast Age Context in The Death Cure
The story centers on young adults in their late teens to mid-20s, and the cast members were deliberately cast near their actual ages to preserve authenticity. Dylan O'Brien's performance reflects this emphasis on youthful determination amid the maze and WCKD's experiments.
- Dylan O'Brien born 1991, turning 25 during 2016 principal photography.
- Kaya Scodelario and Thomas Brodie-Sangster were also in their mid-20s, aligning their onscreen and offscreen ages.
- Production delays meant that cast members aged several years between script drafts and final filming.
Comparison With Previous Maze Runner Releases
The first two films condensed the story into a tighter shoot, so age questions were less prominent. In The Death Cure, the timeline stretches across years, which makes Dylan O'Brien's exact age during filming a frequent point of clarification.
| Film | Release Year | Dylan O'Brien's Age at Time of Theatrical Release | Notes |
|---|---|---|---|
| The Maze Runner | 2014 | 22 | Younger character portrayed by a younger actor |
| Maze Runner: The Scorch Trials | 2015 | 24 | Filmed back-to-back with high continuity |
| Maze Runner: The Death Cure | 2018 | 26 at release; 24–25 during principal photography | Extended production and release gap |
Clarifying Confusion Around the Age Question
Because The Death Cure was announced years before it reached theaters, and because filming occurred in separate blocks, some sources cite Dylan O'Brien as 24, 25, or 26 when discussing the role. The most accurate answer focuses on the primary shooting period in 2016, when he was 24 turning 25. This aligns with the film's internal timeline and casting choices.
Summary
During the principal photography of Maze Runner: The Death Cure in 2016, Dylan O'Brien was 25 years old for most of the shoot and turned 24 during early filming. This answers the question of how old he was in Maze Runner 3 with precision and supports long-term accuracy for searches about his age, the film's timeline, and cast details.
