The film, in which Dornan plays Christian Grey, is out next week – following the huge success of 2015’s Fifty Shades of Grey and 2017’s Fifty Shades Darker.
But despite a shift in tone – this film is ostensibly more of a thriller than a romance – it seems the erotic scenes are out in full force.
Speaking to Ellen DeGeneres on her US chatshow, he said: “The third one feels like a different genre. There’s still sex in it! We’ve kept a fair amount.
“Someone was telling me there’s more sex in the third one than any of the other two.”
He joked: “But I don’t sit there with a timer so I don’t actually know the answer to that.
“But there’s definitely a thriller aspect to this. Someone gets kidnapped.”
Dornan also said that his wife, Amelia Warner, has still never seen him as Christian Grey.
“She hasn’t seen the movies or anything,” he admitted. “I don’t want to pay for her ticket…!”
Dornan appeared on Jimmy Kimmel’s show yesterday, too, and quashed the notion that he and co-star Dakota Johnson don’t get on.
“You have this mutual love and respect for each other,” he said. “We know each other intimately!”
Fifty Shades Freed is out on February 9.
