Jamie Dornan has confessed that he "followed a woman off a train one day" to prepare for his role as serial killer Paul Spector in RTÉ/BBC drama The Fall.
The Fifty Shades of Grey star made the admission during a live chat with the LA Times as he explained how he attempted to get into his psychotic character's mindset.
"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..." Dornan began the anecdote before trailing off and asking: "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 confessed.
Dornan stressed that he kept his distance from the woman and that once she reached her stop, he lingered behind her for only a few yards. He admitted: "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?'"
The BBC recently confirmed that The Fall will return for a third season in 2016.
