His worried apparently started as soon as he ready director Richard Curtis’ screenplay for the 2003 film.

“I saw it in the script and I thought, ‘Well, I’ll hate doing that,'” Grant said. “I didn’t fancy doing the dance at all, let alone rehearsing it.”

Curtis joked, “He kept saying no. I think he was hoping I’d get ill or something and we’d say, ‘Oh, well, what a shame, we’ll have to lose that dancing sequence.'”

The director said Grant “was grumpy” about it, but that “it was a contractual obligation.”

“A contractual guillotine, yes,” Grant said. “And I’m out of rhythm, by the way, especially at the beginning when I wiggle my ass.”

Talking about his dance moves in the scene, the actor admitted, “And to this day, there’s many people — and I agree with them — who think it’s the most excruciating scene ever committed to celluloid. But then some people like it.”

The interview is part of the upcoming ABC News special “The Laughter & Secrets of Love Actually: 20 Years Later”, airing Nov. 29.
