"Fifty Shades Of Grey" stars Jamie Dornan, 32, and Dakota Johnson, 25, are set to grace the cover of the March issue of the Glamour UK magazine, which will be on sale on Feb. 3.
In an interview with the magazine, Dornan revealed some of the things he did to prepare for his role as Christian Grey in "Fifty Shades Of Grey."
"One rainy Tuesday evening, I kissed my wife and baby goodnight and went to watch a dominant-submissive session in a dungeon. The dominant was our sort-of advisor on the job. So I watched him do his thing," Dornan said.
Although watching the dominant-submissive session was helpful to a point, Dornan said he did not enjoy it massively.
While filming the Fifty Shades Of Grey," the Irish actor said there were times when Johnson was not wearing much, and he had to do stuff to her that he would never choose to do to a woman.
"When my daughter's 18, I'm not going to be going, 'You've gotta watch Daddy in 'Fifty Shades Of Grey.' But there will be greater things to protect her from than Dad's arse on the big screen," Dornan also told the magazine.
On the other hand, Johnson said it was "stressful enough to be tied to a bed naked in a scene" Dornan would be the first one to throw a blanket over her.
Also featured in the film adaption of E.L. James' best-selling erotic novel is Luke Grimes, who was recently spotted at a restaurant in Paris called La Table after the launch of The Webster Miami x Le Bon Marché Paris collaboration, Style reported.
