8. The Dancing Prime Minister (Love Actually)
One of humanity's most beloved Christmas films, Love Actually is stuffed full of warm festive cheese that can melt even the steeliest of hearts. It also has Hugh Grant dancing, which makes any film ten times better.
And yet, strangely, the actor full-on hated the idea of performing the scene, so much so that he tried to wriggle his way out of it on several occasions, and only ended up shooting it when writer-director Richard Curtis convinced him to play ball.
Grant was reluctant to film the scene because he couldn't quite grasp the technicalities of it - mainly, he didn't understand how his character could hear the music throughout the house, considering said music was being played from one room:
“I never understood it technically. I kept saying to Richard [Curtis, the director] ‘Okay look, I got the radio on in my bedroom and I’m dancing fine but then I start to dance through the whole 10 Downing Street. Where’s the music coming from and how does it cut off at the end?'"
He even tried to get out of rehearsals by saying he had a bad ankle, and had the actor stood firm with his dislike of the scene, there's a chance that it might never have happened at all. Bah humbug! Where's your festive spirit, Grant?!
