In 2003, the 1978 television series, Battlestar Galactica was brought back to the small screen in what was termed a "reimagined" form, as a three-hour miniseries. The project was written and produced by Ronald D. Moore and directed by Michael Rymer. Alessandro Juliani starred as Felix Gaeta, a lieutenant in the Colonial Fleet. The miniseries effectively served as pilot for a potential TV series which was later commissioned in a collaborative effort between the Sci-Fi Channel and Sky TV (the British broadcaster). Battlestar Galactica (2004–2009) was filmed mostly in Vancouver, British Columbia, Canada.
In the episode "Guess What's Coming to Dinner?", Alessandro's vocal skills were featured prominently. His character's singing is explained as a method of dealing with the pain of a severe physical injury. His voice is heard often when flashing through other scenes and characters.
Juliani sings in Gaeta's Lament, the first track of the Battlestar Galactica Season 4 soundtrack.
