Lucy Lawless' first appearance on the show and one of the few times she uses her own native Kiwi accent on a US show.
The music accompanying the end of D'anna Biers documentary video on the Galactica, which starts with a janitor whistling the tune and ends in a triumphant fanfare, is the theme song from the original "Battlestar Galactica" (1978). It was last heard during a Viper air show ceremony in the new series' pilot miniseries; within the new series' storyline, the old theme song is the national anthem of sorts for the Colonials.
The documentary crew's camera is actually a cosmetically altered Panasonic DVX-100 (or possibly the 100A). Also, the video tape that Biers conceals is a regular MiniDV cassette.
The theme song heard before Baltar's interview is based on the theme song of the original TV 1978 TV show Battlestar Galactica.
Opening credits say there are 47,853 human survivors.
