Turns out, babies are a major stress reducer. Sometimes.

Taking on the role of Christian Grey -- the billionaire, BDSM-loving protagonist of "Fifty Shades of Grey" -- was never going to be an easy task for anyone. The book has already sold more than 100 million copies, making Christian a widely known object of sexual desire for women (and men!) worldwide. Jamie Dornan knew this when he accepted the part in Sam Taylor-Johnson's film adaptation, but lucky for him, he was just a little bit too busy to get fully stressed out.

"There was four weeks from being cast to filming it, and that was like, getting to Vancouver," Dornan, who filled in last minute when Charlie Hunnam suddenly dropped out, told MTV News. "My wife was very heavily pregnant at the time, so we had to get to Vancouver, have a Canadian baby. It was kind of a mad time, and most of my energy was taking care of my wife, and when our baby came, taking care of her... it was good to have something else to focus on to take away that pressure, in a way."

And at the end of the day, Dornan says he felt confident that the gazillions of "Fifty" fans would be satisfied with his blood, sweat and tears.

"We were trying to satisfy the fans," he said. "At the very core of everything that we did with the movie, it was just like, 'Let's give these fans what they want.' There might be people who I'm not their ideal, or I don't fulfill whatever their fantasy was of this guy, but I can't do anything about that."

"Fifty Shades of Grey" is currently playing nationwide.
