The touching tributes, fond memories and fun details from the lives of extraordinary showbiz mother-daughter duo Carrie Fisher and Debbie Reynolds are still being shared – from deep dives into Fisher's under-reported gigs as a script doctor to the fact that her ashes were, as per her wishes, recently buried in an urn shaped like a giant Prozac pill. And tonight, another tribute, one years in the making, will have its unfortunately timely premiere. 

At 7 p.m., HBO will air the broadcast debut of Alexis Bloom and Fisher Stevens' documentary "Bright Lights: Starring Carrie Fisher and Debbie Reynolds," an intimate glimpse inside the two actresses' older lives, merrily living next to each other in adjoining houses, as well as a look back at the impressive Hollywood careers that led them there. 

The doc originally premiered last May at the Cannes Film Festival, to strong reviews. And even though it's pretty much impossible to watch the trailer for the doc without a new sense of sadness – especially when Fisher talks about being concerned about her mother's ailing health – "Bright Lights" looks less like a mournful in memoriam (quickly added slate in the beginning not withstanding) and more like a sweet, delightful, "Grey Gardens"-y hangout with two Hollywood legends, talking about their lives in showbiz – then and now – in that peppy, honest and hilarious way we loved them so much for. 

With their unexpected deaths bringing last year's brutal run to a close, it only seems right that a hopeful new year opens with a tribute to their bright and bold lives, on and off the screen.
