"We got naked, but Idris asked me to keep my socks on," she revealed. "I thought he didn't like feet, but it is the opposite. Idris loves feet!"
"I've just got a bit of a thing," Elba bashfully replied.
The 45-year-old British actor has talked about having a foot fetish before, telling GQ that his 2013 TV play, Pavement Psychologist -- which he wrote and directed -- was based on his love for feet. Actress Anna Friel plays a woman obsessed with shoes in the play, and Elba told the magazine that he sought the advice of none other than Vogue Editor-in-Chief Anna Wintour.
"Anna's so funny. She said, 'It's a good script, but why feet?'" he shared. "I had to be honest with her. There came a moment right there where the actor was looking at me and saying, 'Why did you write this story?' And I had to say, 'Well, I've got a f***ing fetish for feet.' I spilled the beans, told the truth about it. I know how it developed and when, and I've never articulated it and it just seeped into that script."
