What a gift this will be.

Having premiered at the 2016 Cannes Film Festival, mere months before the unexpected and tragic passing just one day apart of this mother/daughter pair of Hollywood icons, HBO has now sped up its air date for this well-reviewed documentary from the spring to this week.

Even though the trailer is light-hearted, you may need tissues for it.

Bright Lights: Starring Carrie Fisher and Debbie Reynolds premieres on Jan. 7 at 8 p.m. ET on HBO.
