“Maleficent” is one of this year’s hotly anticipated films–and has been since the first photos of Angelina Jolie dressed as the wicked lady surfaced online last year–but now a new trailer has been released that features a sweetly haunting cover of “Once Upon A Dream”, and the song, which was leaked on Tumblr before its official release, has taken the web by storm.

The tune is done by Lana Del Rey, whose dreamy voice goes perfectly with the song’s subject matter. Del Rey is rumored to have been hand-picked by Angelina Jolie herself to cover the song, which is the perfect backdrop for the trailer.

The film stars Elle Fanning as the fair-haired beauty and will be released on May 30. According to the synopsis:

“A beautiful, pure-hearted young woman, Maleficent has an idyllic life growing up in a peaceable forest kingdom, until one day when an invading army threatens the harmony of the land. Maleficent rises to be the land’s fiercest protector, but she ultimately suffers a ruthless betrayal—an act that begins to turn her pure heart to stone. Bent on revenge, Maleficent faces an epic battle with the invading king’s successor and, as a result, places a curse upon his newborn infant Aurora. As the child grows, Maleficent realizes that Aurora holds the key to peace in the kingdom—and perhaps to Maleficent’s true happiness as well.”
