Emma Watson’s hilarious childhood habit almost wrecked Harry Potter filming

Emma Watson has revealed that she would ruin takes during the first Harry Potter film by accidentally mouthing along to her co-stars' lines. The 26-year-old was left red faced on the Jimmy Kimmel Show when Jimmy played a clip from the film in which Emma can be seen mouthing along with Daniel Radcliffe and Rupert Grint, and Emma opened up about how the habit "created issues" during filming.

"You laugh! This is actually quite traumatic for me because I created issues because of this," the Perks of Being a Wallflower actress said. "I would ruin takes! Chris would be like, 'Cut! Emma, you're doing it again. You're mouthing Dan's lines.' And I'd be like, 'Oh! I'm sorry. So sorry. Oh, I feel so bad.' But I couldn't help myself! I was such a loser. I really loved those books, I really wanted to do my job well and I overdid it."

The star, who joined the Harry Potter franchise when she was just nine, spoke fondly about the experience, telling the chat show host: "No one goes to the first audition they've ever been to in their entire life and makes those movies for over a decade – it just doesn't happen." Emma's latest role is as the beloved Disney princess Belle in Beauty and the Beast and she recently revealed how the character has been updated for a modern audience. "In the animated movie, it’s her father who is the inventor, and we actually co-opted that for Belle," she explained to Entertainment Weekly. "I was like, 'Well, there was never very much information or detail at the beginning of the story as to why Belle didn’t fit in, other than she liked books. Also what is she doing with her time?' So, we created a backstory for her, which was that she had invented a kind of washing machine, so that, instead of doing laundry, she could sit and use that time to read instead. So, yeah, we made Belle an inventor."
