Jamie Dornan has revealed he was "smitten" with wife Amelia Warner from the moment he met her.
The couple married in 2012 and have a 19-month-old daughter, Dulcie.
When asked if there was anything about his wife that irritated him at the start but he has now learned to love, Jamie said "no".
"I was smitten from the start, I really was. I'm more in love with her today than I was at the start, so no," he said.
Amelia has been hugely supportive of Jamie's career and moved to Canada a week after Dulcie was born so they could be with him while he filmed Fifty Shades of Grey.
When asked about his plans for the future, Jamie said the couple would like to have more children.
The Northern Irish actor is currently promoting his next film called Anthropoid.
The World War II movie also stars Irish actor Cillian Murphy and is set to start filming in the Czech Republic next month.
Dornan will play Jan Kubis, a Czechoslovakian soldier who attempted to assassinate Reinhard Heydrich in 1942.
Heydrich, known as 'The Butcher of Prague' was a high-ranking German Nazi official during World War II and one of the main architects of the Holocaust.
The movie is named after the real-life Operation Anthropoid in which two Czechoslovak paratroopers, who had been trained by the British forces, attacked Heydrich's car in Nazi-occupied Prague in 1942.
Heydrich died several days later and it prompted the reprisal killing of thousands of civilians.
Dornan said he could relate to this character in a way that he couldn't with serial killer Paul Spector in The Fall.
"There are things about Jan that will make sense to me more personally rather than having to really dig too far. He's a man with a mission to carry out and it's a mission for the right reasons," he said.
"It's not someone like Spector who is murdering people just for no good reason… this is murder in a sense, but it's for a greater good."
He said he views his and Murphy's characters as "heroes" and that gave him the motivation to take on the role.
"They're heroes in the sense of what they did, but very much you see that they are flawed, and have very human aspects to them that would hinder trying to carry out an exercise like this," he said.
"You always need a drive and a reason to tell the story. As an actor, you've got to have something that drives you every day on the set."
