Jamie Dornan drank beer while his BDSM consultant ''got to it''.

The 32-year-old Hollywood actor, who stars as Christian Grey in 'Fifty Shades of Grey', has revealed he watched BDSM expert Liam Helmer as he prepared to play the role of the male protagonist from the erotic novels by author E.L. James.

He explained: ''We had a guy called Liam and I sat in the corner with my beer, and they got to it.

''The one thing I took away from it was that it was incredibly playful, not so terribly serious.''

However, Jamie - who stars alongside Dakota Johnson in the new film - admits he didn't find the scenario to be very sexy at all.

He told The Sun newspaper: ''It was all very strange.''

Meanwhile, Jamie recently confessed he plans to keep a low profile once he has finished promoting the new film, saying he won't be sticking around London to canvas the public's opinion of the movie.

He said: ''I am fleeing the country. I am certainly not going to stand in Leicester Square without my shirt, asking people if they enjoyed the movie! I am keeping a low profile.''

He also revealed that his wife, Amelia Warner, wouldn't be going to see the movie in the cinema.

He said: ''She hasn't seen the film and I don't think she will, to be honest. I'd understand if she didn't want to.''
