A brand-new teaser for Maleficent debuted during the Grammy Awards, and it stole the show. In addition to stars Angelina Jolie and Elle Fanning, the 90-second spot features Lana Del Rey's cover of the iconic "Once Upon a Dream." I never would have thought of Del Rey as an artist to accompany the Disney film, but her haunting vocals work perfectly with the film's creepy tone. Side note: is this movie for kids? Because we're already scared of Jolie as the evil queen.
