The Fifty Shades star confessed to stalking a woman to prepare for his continuing role in BBC's The Fall, in which he plays serial killer, Paul Spector.
"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 said, before pausing and seeming to think better of his decision to spill the shocking details.
"Can we get arrested for this? Hold on… this is a really bad reveal," he continued. "I, like, followed a woman off the train one day to see what it felt like to pursue someone like that."
But it gets even creepier than that — Dornan admitted he enjoyed the thrill of the act.
"It felt kind of exciting, in a really sort of dirty way," the British actor added. "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?'"
All this despite prior admissions that he doesn't want to play a serial killer forever.
"You don't want to be in that headspace all the time," Dornan said during an interview with the Mirror in 2013. "Certain actors would but I remember thinking I was in over my head when they cast me. I don't want to play a serial killer for the rest of my life but this will change perceptions of who I am."
Between this incredibly creepy revelation and his role as Christian Grey, it sounds like Dornan definitely has a type of role he's best at.
