Charlie Hunnam has said he isn't too worried about the steamy sex scenes in the 50 Shades Of Grey movie.
The actor has been cast as Christian Grey in the movie adaptation of EL James' best-selling book - which has been dubbed 'mummy porn' - but said he isn't phased by the graphic content after starring in racy 90s TV series Queer As Folk.
He said: "You know what, I had such a baptism of fire with regards to sexuality on camera at the beginning of my career.
"I starred in the British Channel Four miniseries Queer As Folk where I played a young, gay character and there were some incredible, explicit sex scenes on that show. Now I am 16 years older and more mature so I don't anticipate them being too much of a problem. It's like anything else, just an exciting challenge."
Charlie, 33, was cast as the kinky billionaire after months of speculation. Dakota Johnson has been cast opposite him as Anastasia Steele.
The Sons Of Anarchy star said he was initially concerned that the timing wasn't right.
"There was a bit of a timing issue where I just wanted to insure that I was going to have enough time to really do the preparation so I can bring this guy to life and do him justice and when they decided to push the schedule to accommodate that then I was a no-brainer and I was in," he said.
He confessed his real-life girlfriend Morgana McNelis isn't particularly excited about him filming explicit love scenes with Dakota.
"Of course, it's difficult being with an actor, you know?" said Charlie. "She is required to share certain parts of me with the world that she wouldn't necessarily choose to do, but we have a great relationship and she loves me and wants to be with me and we've been together a long time now, and I think she understands and has come to terms with the fact that there are certain elements of me that she is going to have to share.
"This is an extreme example of that, but thankfully we do have seven-and-a-half years of history together, so it won't be a big problem."
Directed by Sam Taylor-Johnson, the film is to be released next August.
