'Fifty Shades Of Grey' star admits to stalking woman at train station

As if acting as a sadomasochist in the box office hit 'Fifty Shades Of Grey' isn't enough, Jamie Dornan has revealed he will be playing a 'sick psychopath' named Paul Spector in the upcoming flick, 'The Fall'.

The 32-year-old actor admitted he was forced to stalk a strange woman he spotted on the train in order to get fully prepared for his new role.

Dornan told the LA Times: "On the tube, which is our underground system ... 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 later asked the interviewer, "Can we get arrested for this?"

The actor did admit it helped him fully understand his character better saying, "I followed her for a bit and it felt kind of exciting, in a really sort of dirty way... I'm sort of not proud of myself."

About how 'easy' it is to play a sex pervert in 'Fifty Shades Of Grey' and a serial killer in 'The Fall', the married star previous told The Guardian Newspaper that, "It kinda worries me sometimes how comfortable I am in that zone".
