After the sudden deaths of Carrie Fisher and Debbie Reynolds last week, HBO pushed up the release of its documentary Bright Lights: Starring Carrie Fisher and Debbie Reynolds, which was shot in 2014 and 2015 and focuses on the pair’s mother-daughter relationship. In the trailer, Fisher prepares for her work on Star Wars: The Force Awakens (or Star Wars Seven … ty Two, as she calls it), while Reynolds continues to perform, prepares to receive her SAG Lifetime Achievement award, and refuses to update her cell phone. Fisher died on December 27 after suffering a heart attack on an international flight four days earlier; her mother, Hollywood icon Debbie Reynolds, died one day later of a stroke at 84. The documentary premieres January 7 at 8 p.m. Bring lots of tissues, and don’t forget to call your mom!
