The 34-year-old Northern Irish actor and 59-year-old American television personality substituted office supplies for sex toys while poking fun at the Fifty Shades series on The Ellen DeGeneres Show.
"You've finished filming the next two [Fifty Shades] movies, but if you are going to do a fourth, which I'm sure you are, I have an idea for it," DeGeneres said. "It's a little scene that I wrote, which I thought we could act out."
The Ellen host reappeared in a Staples uniform with fake cleavage and proceeded to "seduce" Dornan on a bed onstage. She taped the star's hands to the bed frame before cutting his tie in half.
"You know, I'm not really into that," the actor said of a stapler remover. "I don't think anybody's into that."
Dornan plays BDSM-loving businessman Christian Grey in the Fifty Shades films, which co-star Dakota Johnson as Anastasia Steele. He recently admitted in the Feb. issue of GQ Australia that he doesn't find BDSM appealing.
"It's doesn't float my boat," the star said before qualifying, "I've always been open-minded and liberal -- I'd never judge anyone's sexual preference. Whatever gets people off is entirely up to them."
The Fifty Shades movies are based on the erotic book trilogy by E.L. James. Fifty Shades Darker, which opens Feb. 10, was preceded by Fifty Shades of Grey, and will be followed by Fifty Shades Freed in 2018.
