Is it even Christmas if you haven't re-watched Love Actually yet? (Spoiler alert: the answer is no).
As it turns out, the beloved festive cult classic could've been quite different had director Richard Curtis not made a last-minute change to the script that involves Martine McCutheon's foul-mouthed Natalie.
Curtis sat down with star Martine McCutcheon as part of Comic Relief's Love Actually Christmas Quiz – and revealed why the change was necessary.
"When I was writing the film, I was absolutely determined that Martine was going to play the woman that Hugh Grant fell in love with," he said. "And it was only when we were about to have the read-through, which is actually sort of going to be her audition, that I suddenly realised I had called the character Martine.
"So literally the day before, we did that sort of 'change all' thing on the computer. [We] changed everything to Natalie suddenly, and then hoped it would be okay, because we didn't want Martine to see the part was for her and then do so badly and be sad for the rest of her life."
Obviously that didn't happen, as Curtis was quick to add, saying: "But she was absolutely perfect at the read-through, as we expected."
