It's time to stop running.

After four years together, the stars of the popular "Maze Runner" movie series are struggling to say goodbye to their characters -- and to each other -- with the final installment of the trilogy, "The Death Cure."

"It's not hit me yet," Kaya Scodelario tells Made in Hollywood reporter Julie Harkness Arnold.

"I don't think it will for awhile," adds Dylan O'Brien. "We're in our denial stage a little bit without even knowing it."

He pauses: "Although I just said it."

In "The Death Cure," O'Brien's Thomas leads escaped Gladers on their final and most dangerous mission: breaking into the legendary Last City, a WCKD-controlled labyrinth that may turn out to be the deadliest maze of all.

Making the movie subjected the cast another round of stunts so perilous that O'Brien suffered a head injury that shut down production for months while he recovered.

"These have always been really tasking movies to make," he says. "I've wondered if I had my step counter, especially on the first one, how many it would say at the end of those longest days. I think it would be insane. But that's part of the challenge, part of the fun and life of these films. That's such a huge aspect of it. We're always in it together. For the most part it's always something we're cracking up about, just trying to get through."

It's these kinds of experiences that have made the cast so close, says Thomas Brodie-Sangster.

"It's hard for for the movies to be ending," he says. "But at least we have this family bond to hold onto."
