ITV’s Until I Kill You is a true story based on the harrowing experiences of Delia Balmer, who started dating John Sweeney and was repeatedly assaulted and almost killed by him.
The show is based on Balmer’s memoir titled Living With a Serial Killer. It follows the early hopeful days of Delia's journey with John to the gradual descent of their relationship with John’s abuses, and Delia’s fearing his return.
Anna Maxwell Martin and Shaun Evans star as Delia and John, and the drama focuses more on Delia’s perspective as it tells the story of how she rebuilt her life after the assaults.
Reflecting on the importance of the story being told from Delia’s point of view, Anna Maxwell Martin said:
"She didn’t take any crap, she’s so resilient and fiery, such an individual, let’s celebrate that rather than showing more gratuitous violence against females on TV. I think we’re all a bit bored of watching that and following predatory male killers around on TV, I didn’t really want to focus on the abuse."
She further mentioned:
"We’re getting inside the mind of a woman who went through a lot of very complex things, not just to do with John Sweeney, and I’m very proud of the drama."
Besides Anna and Shaun, actors like Kevin Doyle, Lucy Thackeray, and Amanda Wilkin are in the cast of Until I Kill You. Let us now look at the cast list and who plays whom in the new true-crime show.
