Jamie Dornan worries about being comfortable in 'Fifty Shades' role

Actor Jamie Dornan finds it odd that he is "comfortable" playing dark and complex characters when in real he is an easy-going person.

Dornan rose to fame with his portrayal of Christian Grey in erotic-romance Fifty Shades of Grey, adapted from EL James's book of the same name. Earlier he played a serial killer in The Fall.

"I consider myself quite light-hearted, pretty easy-going, and I keep playing sick psychopaths. It kinda worries me sometimes how comfortable I am in that zone," Dornan told the Guardian.

The Irish actor said he sometimes finds it comical that he brought Grey's character to life on screen.

"There are times when I'll be like, 'Huh, someone made a Fifty Shades movie, that's funny.' And then I'll be like: 'Wait, I'm the guy?!'"

Dornan, 32, and actress Dakota Johnson will be a part of the two follow-ups to Fifty Shades of Grey.
