Watch The Trailer For HBO’s Documentary Bright Lights: Starring Carrie Fisher and Debbie Reynolds

When Carrie Fisher and her mother Debbie Reynolds passed away late last month a day apart, Hollywood felt its heart break. It was a sad, unexpected event that put a cloud over the holidays for many of their fans. The pair had been close throughout their lives, and to celebrate their impact on the silver screen they were the subject of an upcoming documentary called Bright Lights: Starring Carrie Fisher and Debbie Reynolds. Originally plans were for it to debut on American television in early Spring, but to help celebrate their lives after their untimely deaths, HBO has moved up the premiere to January 7th. Now the first trailer for the doc is out, and it shows us why we need to watch it.

Bright Lights: Starring Carrie Fisher and Debbie Reynolds is about the relationship between mother and daughter. You catch a glimpse of the two talking about old cell phones, and forgetting things. Reynolds discusses Fisher’s problems with mental illness and how she dealt with it. And Fisher herself talks about how she went too far, too fast. Fisher was 60 when she passed away days after suffering a heart attack during a flight from London to Los Angeles. Reynolds was 84 when she died after being hospitalized a day after her daughter passed away.

HBO will air the documentary this Saturday, January 7th.
