Lista de episodios de Battlestar Galactica (serie de televisión de 1978) y Galactica (1980)

Between 1978 and 1981, episodes were edited into three feature-length films. The first film, Battlestar Galactica, was an edited version of the pilot, "Saga of a Star World", featuring some differences from the original televised episodes, including the death of Baltar. It was released in cinemas in Canada, New Zealand, Australia and continental Europe before its American TV premiere and, in 1979, it was released theatrically in the UK, Ireland and the US. The second film, Mission Galactica: The Cylon Attack, was a re-edited version of the episodes "The Living Legend" and "Fire in Space", which also differed from the broadcast versions, omitting several scenes from both episodes. In 1979, it was released theatrically in continental Europe and Japan, and in the UK, New Zealand and Australia in 1980. The third film, Conquest of the Earth (also called "Galactica III" on the German poster), was a similar edit, though this time its source episodes were from Galactica 1980. It was also released theatrically, in 1981, in Europe, New Zealand and Australia.

Tras la cancelación de la serie, todos los episodios originales se reeditaron como películas para televisión para su distribución, incluyendo una tercera versión del piloto. Los cuatro episodios de dos partes ("Lost Planet of the Gods", "Gun on Ice Planet Zero", "The Living Legend" y "War of the Gods") se combinaron y ampliaron, eliminando aproximadamente cinco minutos de escenas de las emisiones originales. Los episodios restantes se editaron en bloques de dos horas, combinando dos episodios en una sola narración, incluyendo ocasionalmente diálogos doblados. La última película para televisión, una versión ampliada de "Experiment in Terra" con algunas escenas del episodio de Galactica de 1980 "The Return of Starbuck", presentaba nuevas imágenes de un astronauta encontrando el diario de a bordo del Comandante Adama, que retomaba la premisa de la serie. Se cree que esta versión del episodio iba a estrenarse como película en cines en otros países, pero nunca llegó a materializarse.
