What Dylan O'Brien has been up to recently

Following an accident on the set of The Maze Runner: The Death Cure, the actor took a little hiatus from the spotlight since Teen Wolf.

In March 2016, while filming the Maze Runner's opening sequence, O'Brien was injured when a harness malfunctioned during a stunt scene. In September 2017, he told The Salt Lake Tribune that the incident "damaged most of the right side of my face." He's now speaking up about how the incident affected his life. He said:

"I had friends that were so dear to me that I had felt that I had neglected for years. All of a sudden, it was very important to me to nurture those relationships and not lose them. I think that it absolutely completely rewires and restructures the way you see your life and what you deem important."

After recovering from his accident, O'Brien starred in the 2017 film American Assassin before finishing The Maze Runner: The Death Cure in 2018.

Since then, the actor has remained relatively quiet. But in May 2020, he made a spectacular return to social media by replying to one of Halsey's throwback tweets.

He has starred in movies like Love and Monsters and Flashback in titular roles. He also appeared in the second episode of Season 11 of the HBO series, Curb Your Enthusiasm.

Dylan O'Brien also appeared in All Too Well: The Short Film, released in November 2021, alongside Taylor Swift and Sadie Sink.

Dylan O'Brien will star alongside several notable actors in the upcoming film The Outfit, premiering in March 2022.
