I stalked a woman to prepare for my role: Jamie Dornan

Los Angeles: "Fifty Shades of Grey" star Jamie Dornan stalked a woman to prepare for his role in BBC's "The Fall".

The 32-year-old actor, who played serial killer Paul Spector in the hit show, said he got into character before getting on set by actually following a woman, reported Us magazine.

"The first series, I did do a couple of things to try to get inside (his mind). On the tube, which is our underground system. Can we get arrested for this? Hold on... This is a really bad reveal: I, like, followed a woman off the train one day to see what it felt like to pursue someone like that," he said.

"It felt kind of exciting, in a really sort of dirty way. I'm sort of not proud of myself. But I do honestly think I learned something from it, because I've obviously never done any of that. It was intriguing and interesting to enter that process of 'What are you following her for?' and 'What are you trying to find out?'," he added.
