‘Vox Lux’: Natalie Portman Sings Original Ballad by Sia in New Trailer (Video)

“Wrapped Up” is performed by Portman’s pop star character Celeste in Brady Corbet drama

Jam alert! We’ve finally got a glimpse of Natalie Portman singing in a new trailer for “Vox Lux.” And the track, an original power-pop ballad from Sia, is going to get stuck in some heads.

Sia’s song is “Wrapped Up,” which is featured prominently in the second trailer for Brady Corbet’s art house drama “Vox Lux.” It’s a stirring, emotional anthem about how embracing others keeps you away from your darkest impulses and fears.

“Turn the light on, because I’ve got no one to show me the way,” Portman sings. “And I’m so lucky to be with you keeping me from my shadow.”

But the song clearly has a big story connection as well. Portman’s pop star Celeste introduces it at a concert as “going back to where it all started,” followed by a stark smash cut to a teenage Celeste performing the song at her friend’s funeral vigil. The film both follows Celeste as a teenager performing with her sister after surviving a violent tragedy and her as a 31-year-old mother to a teenage daughter of her own as she struggles to navigate her career as an aging pop star.

“I keep feeling like big moments keep getting stolen away from me,” Portman says in the trailer. “You know sometimes you just get kicked while you’re down.”

“Vox Lux” also stars Jude Law, Stacy Martin and Christopher Abbott. The film opens on Dec. 7 in limited release before expanding everywhere on Dec. 14.
