DEBBIE AND CARRIE, A HOLLYWOOD LOVE STORY.

ELIZABETH VARGAS (ABC NEWS) (Off-camera) Good evening. I'm Elizabeth Vargas in Los Angeles. David is away. As you can see, I'm looking down on the fabled Hollywood Boulevard where movie fans have been laying tributes at the walk of fame star of Debbie Reynolds. In the last few days, it's become a makeshift memorial for both mother and her daughter, Carrie Fisher, unbelievably dying just one day apart. And a few hours ago, I spoke to Todd Fisher, Carrie's brother and Debbie's son about their very last hours and the end of a Hollywood era. [ABSTRACT FROM PUBLISHER]
