The 34-year-old Irish actor portrays the sex obsessed billionaire in the 2015 erotic thriller and the upcoming two sequels and the first movie in the franchise made him a global superstar.

And when he's recognised in public people don't know who he is or mention any of his other roles such as serial killer Paul Spector in TV series 'The Fall' or Axel von Fersen in Sofia Coppola's 2006 film 'Marie Antoinette' it's always Christian Grey.

Dornan usually pretends he's not the guy from the film but even when he does admit it fans don't believe him or even recognise his name from the film's credits.

In an interview with Metro newspaper, he said: "It happens more with Christian Grey, though they can't always place me.

"Recently, it was really funny - I was driving back north a few weeks ago with my mates to play golf, and I'd been to a premiere in Dublin for 'Anthropoid'. It got really late, around midnight, so we stopped at a service station in the middle of nowhere for a Burger King. The girl working there looked at me and said, 'Oh my god! You must get this all the time - you're the spit of Christian Grey from those 'Fifty Shades' movies!' I wouldn't normally have done it but it was late, she was serving burgers, so I said, 'Yes, yes, it is me - I'm the actor from those films. She looked at me like I was crazy, pulling her leg. I showed her ID but she hadn't a clue who Jamie Dornan was. She just wasn't having it! That keeps things real."

One person who isn't impressed by his 'Fifty Shades' fame is Dornan's wife Amelia Warner as she has never watched the movie in which he gets hot and heavy with his co-star Dakota Johnson - who portrays Christian's lover Anastasia Steele.

He recently revealed: "My wife is one of the most brilliant human beings in the world. She hasn't watched it. Why would she watch it? She wouldn't put herself through that."
