Today in celebrities try the creepiest things, Jamie Dornan has revealed he once followed a woman off the Tube to prepare for his role as a psychopath in crime drama The Fall.
The actor told the LA Times that the incident happened when he was to get inside the mind of his character Paul Spector.
I, like, followed a woman off the train one day to see what it felt like to pursue someone like that. I really kept my distance, and I was aware - it was kind of half hearted... I followed her around a couple of street corners and then I was like 'what are you doing?'
It felt kind of exciting, in a really 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?' It was interesting.
You can see him talk about the incident from 14 minutes in.
