Sarah Wayne Callies says she was drawn to the journey that her character goes on in The Other Side of the Door when she read the script.
The actress returns to the big screen this week as she takes on the central role of Maria in the new horror film, which sees her team up with filmmaker Johannes Roberts for the first time.
Speaking exclusively to FemaleFirst, she talked about what drew her to the role. She said: For me, it has everything to do with that journey of grief and madness and just how close they are to each other.
"I watched someone very close to me lose a daughter when I was quite young and I never got over the impression that that kind of grief is unpredictable and can change people's minds and hearts in totally unforeseeable ways; their behaviour can be unlike anything you have ever seen before.
"The actor part of me thought that that would be interesting to play and the human part of me thought it would be interesting to try and explore those corners of my own brain."
The Other Side of the Door is the first time that we have seen the actress on the big screen since Pay the Ghost as she continues to move between television and film projects.
The actress will be back later this year with This Is Your Death and will be filming the next season of TV series Colony, which will see her reprise the role of Katie Bowman.
The Other Side of the Door is out now. Read the full interview with Sarah Wayne Callies here.
