The real reason Hugh Grant hated filming iconic Love Actually scene

Hugh Grant hated filming the dance scene, with director Richard Curtis claiming the actor was "hugely grumpy" and "kept on putting it off".

It's hard to pick a favourite scene in the much-loved 2003 movie Love Actually, but most fans would agree the part where Hugh Grant — as David, the Prime Minister — dances around his Downing Street home to Jump would have to be right up there.

However, it was somewhat tarnished in 2016 when director Richard Curtis revealed that Grant had really hated filming the scene, claiming the actor was "hugely grumpy" and "kept on putting it off."

After presumably copping heat from fans, Grant himself has now clarified exactly what his problem was — and it was all about the logistics.

"I kept saying to Richard [Curtis, director]: 'Okay, look. I've got the radio on in my room, my bedroom. And I'm dancing, fine. But then I start to dance through the whole of 10 Downing Street. Where's the music coming from? And how does it cut off at the end?" he told PeopleTV in a new interview.

According to Grant, Curtis brushed his concerns, telling him: "Oh, don't worry about all that. It's film world."

Here are some other facts about your favourite movie that you probably didn't know:

Love Actually was meant to be two separate films

The director once told Vulture that he was originally working on two films, one about Hugh Grant's character and the other about Colin Firth's character. "I'd worked out whole films on those subjects, and then I thought, 'Oh, I don't want to do these because they are just turning out to be a shape I know'," Curtis said.

The movie stole a scene from Four Weddings and a Funeral

The scene where Colin accidentally insults the caterer's food to her face while attempting to flirt was originally written for Grant's character in Four Weddings and a Funeral, but was cut in the final stages of editing — so it was recycled.

Claudia Schiffer was never supposed to be in the movie

The original script referred to the blonde character as someone who looked similar to Claudia Schiffer. But the director had trouble finding an actor who fit the mould, so they approached the supermodel to see if she was interested.

"It was funny how it ended up, you know, him getting the real deal. I just thought it was brilliant," Love Actually star Elisha Cuthbert said to VH1.com.

The airport scenes at the beginning and end of the movie are real people

The crew had cameras set up at Heathrow Airport for a week filming real people as they greeted their loved ones.

Curtis told Vulture: "That was real documentary footage that we shot without anyone knowing we were shooting, and we had to rush up to people and ask for their permission to use it."
