'Fifty Shades' Star Prepared For Serial Killer Role By Stalking Woman

If you were freaked out by Christian Grey's perversity before, this is really going to put you over the edge.

The man who played Grey in "Fifty Shades of Grey," Jamie Dornan, also stars in a television show called "The Fall."

In that program, Dornan plays a serial killer. In order to get inside the character's mind, Dornan actually stalked a woman in real life.

He followed an unsuspecting woman off the train to get a sense of what it would be like to perform the act.

Dornan said,

I like, followed a woman off the train one day to see what it felt like to pursue someone like that. 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.

However, Dornan qualified his remarks by saying he did it from a distance and in a "really half-hearted" way. Still, that's pretty damn creepy.
