The trailer for Bright Lights, the documentary exploring the bond between Carrie Fisher and her mother Debbie Reynolds, has arrived ahead of its January 7th release on HBO. The film carries a more poignant tone following the sudden deaths of both actresses in late December.

In the bittersweet trailer, mother and daughter struggle with cell phones, memory – "That's what so good about losing your memory: There are so many surprises," Fisher quips – and their own mortality. "Age is horrible for all of us. But she falls from a greater height," Fisher says of her mother, a Fifties icon and Singin' in the Rain star, in the trailer. "I'm my mom's best friend. For than I ever would want to, I know what my mother feels and wants. There's a lot of it."

While the preview for the documentary leans toward comedy – "I have to go and start rehearsals for Star Wars Seven … ty-two," Fisher jokes about reprising Princess Leia – Bright Lights has become an ad-hoc memorial for the two actresses who died within a day of each other. Fisher died December 27th, four days after suffering a cardiac episode aboard a Los Angeles-bound plane. The next day, Reynolds passed away on December 28th after a severe stroke.

The mother and daughter will be buried together Thursday following a private joint funeral.
