Jamie Dornan's wife was fully supportive of his decision to star in 'Fifty Shades of Grey'.

The 32-year-old actor has revealed that his ''hugely understanding'' wife, Amelia - who was pregnant at the time with their 14-month-old daughter Dulcie - was happy for him to take on the role of Christian Grey in the novel adaptation.

He told OK! magazine: ''My wife is a brilliant, hugely understanding person. She was an actress for 10 years, so she's aware of what it's like.

''A lot of people would have had a s**t fit at 30-something weeks pregnant hearing, 'Darling, we're going to Vancouver this week for four months - we're going to have a Canadian baby and I'm going to do a film where, for parts of it, I will be naked.' That's a tough pitch, but my wife is an incredible person.''

Meanwhile, Jamie previously revealed that he fears he will be murdered by a ''mad'' fan at the premiere of the erotic film.

He said: ''I almost don't want to put this out there into the ether, but I fear I'll get murdered, like John Lennon, by one of those mad fans at the premiere. Because a lot of people are very angry that I'm playing this character.

''And I'm a father now, and a husband. I don't want to die yet.''
