Four months before the film opens on May 30, Angelina Jolie pledges plenty of evil-doing as the title character in a Disney Channel spot for Disney’s “Maleficent.”

“Disney’s greatest villain comes to life,” the teaser promises.

“Maleficent” is a live-action retelling of Disney’s “Sleeping Beauty” with a focus on the sorceress character. The trailer mixes footage from the 1959 animated film with shots of a vengeance-seeking Jolie donning a cape and horns and other images from the new movie.

Sharlto Copley, Elle Fanning, Sam Riley, Imelda Staunton, Juno Temple and Lesley Manville also star.

“Maleficent” is produced by Joe Roth, directed by Robert Stromberg and written by Linda Woolverton. Jolie, Don Hahn, Matt Smith, Palak Patel and Sarah Bradshaw serve as executive producers.
