Fifty Shades Of Grey star Jamie Dornan has revealed how he stalked a woman on the Tube in preparation for his role as a serial killer in The Fall.
The actor, who appeared opposite Gillian Anderson in the show, said he kept his "distance" and did it in a "really half-hearted" way.
He told the LA Times: "I like, followed a woman off the train one day to see what it felt like to pursue someone like that."
He added: "It felt kind of exciting in a really dirty way and I'm not proud of myself but I do think I learned something from it".
The BBC Two show was critically acclaimed but has also been accused of glamorising violence against women - with its writer saying it "lingered too intimately" on the killer's brutal crimes.
