In an interview with the BBC, Benz described Darla as strong: "I have an amazing stunt double, Lisa Hoyle who looks exactly like me. She’s just brilliant and fearless and she does about 90 per cent of the stunts. I think part of the element of Darla is how strong she is and how fierce she can be and Lisa definitely adds to that element. I would be a doing huge disservice to Darla if I didn’t allow her to do the work that she does and to help add to that element that’s so important to Darla, which is her strength."
