A new teaser for Disney's highly anticipated Sleeping Beauty prequel Maleficent debuted during the Grammys.

During the ad, soundtracked by Lana Del Rey singing "Once Upon a Dream," viewers got more glimpses of Angelina Jolie's titular character's evil powers.

The teaser begins with Maleficent walking through a crowd, ready to bestow her "gift" on princess Aurora. After a full-body shot of her conjuring up evil magic, in the form of green smoke, Maleficent disappears.

But she's later shown walking menacingly through the forest and summoning up grass-and-branches-covered monsters, which later do battle with armored knights unleashed by the castle.

"There is evil in this world, hatred and revenge," Maleficent says in a voiceover as Aurora is mesmerized by a spindle.

The teaser ends with an evil laugh from Maleficent.

Maleficent hits theaters on May 30.
