'Bright Lights: Starring Carrie Fisher and Debbie Reynolds' air date, latest news: HBO releases new trailer; documentary to air on Jan. 7

Following the passing of "Star Wars" legend Carrie Fisher and "Singing in the Rain" star Debbie Reynolds, HBO recently released the trailer for its upcoming documentary "Bright Lights: Starring Carrie Fisher and Debbie Reynolds," which details the lives of the two Hollywood stars as well as their close mother–daughter relationship.

The trailer for the forthcoming documentary film depicts the close relationship between Fisher and Reynolds as they banter about cell phones and losing their memory. It also features glimpses of old photographs and video clips of the mother–daughter tandem in their younger years, while also referencing Fisher's struggle with her mental illness over the years.

On what the documentary will be mainly about, HBO Documentary Films president Sheila Nevins previously told Variety that the film is "a love story."

"Carrie wanted to make 'Bright Lights' for Debbie and Debbie wanted to make it for Carrie," Nevins said.

"Bright Lights" has been completed for quite a while and was previously shown at a few film festivals back in 2016. According to Deadline, the film received audience and critical acclaim at the 2016 Cannes Film Festival, the Telluride Film Festival, and the New York Film Festival, among many others.

As reported by IGN, it was originally scheduled to air on HBO this coming March, but the cable network decided to move up the documentary's airdate to this January in the wake of the sudden and subsequent deaths of Fisher and Reynolds last December.

Fisher passed away on Dec. 27 after suffering from a heart attack during a transatlantic flight from London to Los Angeles a few days earlier. The following day, on Dec. 28, Reynolds also died of a stroke at Cedars-Sinai Medical Center.

"Bright Lights: Starring Carrie Fisher and Debbie Reynolds" is scheduled to hit the airwaves this coming Saturday, Jan. 7, at 8 p.m. ET on HBO.
