28 Years Later spoilers follow.

28 Years Later star Jodie Comer has broken her silence on a devastating moment from the film.

Directed by Danny Boyle and written by Alex Garland, the third film in the horror franchise follows a group of survivors living on a remote island.

When Jamie (Aaron Taylor-Johnson) takes his son Spike (Alfie Williams) onto the mainland for an expedition, Spike learns of an eccentric doctor named Ian Kelson (Ralph Fiennes).

After Spike sneaks his ailing mother Isla (Comer) off the island in search of Kelson, it is eventually revealed that Isla is dying of cancer, and she makes the heartbreaking decision to end her own life.

Speaking to Entertainment Weekly about the death of her character, Comer said: "I felt like there was real agency in that choice."

"You see the journey that she goes on in the movie, let alone what she's probably experienced for the past several years — the kind of inner turmoil and pain," she added.

"It is a very real thing that people come to a point of not wanting to experience that any longer. And I think they're both comforted and held by Kelson in this space."

Comer said that knowing her on-screen son was "okay in this moment" with Kelson meant that Isla "wants to let go", adding: "It's probably hard for us to understand, but it was a complex moment."

She continued: "Even with her trying to protect him, she's withheld a lot from him. And I think that's also a very relatable thing.

"I've had that in my own life, when my parents withheld information from me to try and help me, but in the long run, I've wished that I had that information. So there's a lot going on in that beat, but I think she was ready."
