Hear Natalie Portman Sing A Sia Original In New 'Vox Lux' Trailer

The second trailer for Natalie Portman's upcoming film, Vox Lux, is here, and we're finally getting to hear some of the music from the film. This snippet of the film shows Portman singing a ballad written by Sia.

While the first trailer showed us a more fiery and dramatic version of Portman's character Celeste, this clip gives us more background into her life. In 1999, teenage sisters Celeste and Eleanor survive a school shooting in their hometown of Staten Island. To work through the trauma following the event, the two write and perform a song—which ends up turning Celeste into a star. Fast-forward to 2017, when a grown Celeste is struggling to balance a scandal-ridden career and her own teenage daughter, and "another act of terrifying violence demands her attention."

This trailer features both a teenage and a grown-up Celeste singing the same song. There's a stark difference between her younger self's performance—which is set in a church following the tragedy and witnessed by mourners—and Portman's costumed, dramatic performance. Both, however, seem to be shrouded in a similar darkness.

Vox Lux hits theaters on December 7. Watch the second trailer, above.
