Emma Watson [1] stopped by Jimmy Kimmel Live [2] on Monday night to promote her new film Beauty and the Beast [3], but she actually ended up reminiscing about Harry Potter [4] in the process. During the show, the actress got incredibly flustered when the host played an outtake from the very first film, Harry Potter and the Sorcerer's Stone. Not only does she look so young in the clip, but in true Hermione form, she was actually mouthing all of her costars' lines during the scene. "I couldn't help myself," she said. "I was such a loser. I really love those books. I really wanted to do my job well, and I kind of overdid it."
