The trailer for HBO's Debbie Reynolds-Carrie Fisher documentary is here.

Less than a week after their deaths, HBO has released a trailer of its documentary about Carrie Fisher, her mother Debbie Reynolds, and the intensity of mother-daughter relationship.

Bright Lights: Starring Debbie Reynolds and Carrie Fisher will premiere on January 8, after being brought forward by the network, and follows the bond shared between the two actresses in the years before they passed away one day apart.

Filmed over the course of 2014 and 2015, the documentary bills itself as a “story of the family’s complicated love,” and promises “an intimate portrait of Hollywood royalty in all its eccentricity,” according to PEOPLE.

The 95-minute film uses vintage family films and archival footage to cast a lens on the family's history.

Directors Alexis Bloom and Fisher Stevens say the film was made in the leadup to Reynolds preparing to receive her Screen Actors Guild Life Achievement Award.

“We started out making a film about Hollywood royalty,” they told PEOPLE. “And we ended up making a film about love.”

Its release was brought forward after both Fisher and Reynolds died within two days of each other at the end of December last year.

Fisher, 60, was on board a flight to Los Angeles and died days later on December.

Reynolds died a day later at the age of 84 after being rushed to hospital from her son's home, where they were meeting to plan Fisher's funeral.
