He told Sky News: “It was worrying for me, not only connecting to the creepiness, but also there were just aspects of his character.
“I’m quite a neat freak, and there’s one moment in particular where I think it’s a split-screen where Gugu is putting up her clothes very neatly and Jessica’s character is just throwing them in the top shelf, and I’m so horrified by Jessica’s side of the screen.
“There were definitely moments like that, where I was like, ‘maybe I should go and see the therapist’.”
The Girl Before will start on Sunday, December 19, at 9pm on BBC One.
