In an interview with Details for its February issue, the actor -- playing Christian Grey -- said he actually fears for his life after having snagged the coveted part.
"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," the 32-year-old Irish star said. "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."
All fears aside, Dornan says he does identify with the character of Christian Grey.
"[It had to do with] an attraction and understanding I have for people that are broken in some way," he explained. "Not that I'm some broken bird, but there's a massive element of me that's fractured from losing my mother so young, and I'm drawn to characters who are wounded."
He went on to tell Details that he understands the S&M aspect of the character even if that's not, well, an interest of his.
"Even if you didn't have Christian's history of childhood abuse and abandonment, I totally understand why a person would be into it," he said. "Something like trainspotting or planespotting? I actually don't get that. But I do understand the psychology of being tied up and getting turned on."
