The man chosen to portray Christian Grey from the popular erotica trilogy stopped by the BBC America series to talk all things Fifty, including what he thinks the aftermath will be once the adaptation hits theaters on Valentine's Day next year.
"I mean, look, we're in a really powerful position that 90-plus million people have read the book so if like a third—I mean, a hundredth of those people—that's successful if they go see the film," he said. "It's a nice position to be in, but I have no idea what it's gonna do."
However, the flick already changed the 31-year-old's life in ways he'd never imagined (and it's probably not in the way you're imagining right now).
"So basically, I've always had a complex with the way I walk," the former model revealed. "I've not always been told I've got a bad walk, but someone's always commented on my walk," he continued. "It's always been a bit like, 'All right. That's how you walk?'"
But when he had to prepare for a dance scene with Dakota Johnson, who plays his love interest Anastasia Steele, Dornan was able to finally figure out the proper way to walk when his instructor told him heel-to-toe.
"No one ever told me that!" he exclaimed. "I was always toe-to-more-toe! Now I just apply that every day, when I'm walking around."
The Graham Norton Show, including guests Dornan and Aaron Paul, premieres Saturday, March 8 at 10:15 p.m. on BBC America.
