The ships from the movie Silent Running (1972) were re-used in one episode as "Agro Ships". This was stock footage from the earlier Universal production, as the original (there was only one) was destroyed at the end of filming.
The makeup design for the Borays was used earlier for a similar pig-like alien who greeted Starbuck and Boomer at the Carillon casino in a scene that was cut from "Saga of a Star World". However, the character can still be glimpsed in some shots and the name 'Boray' is used in by another Colonial during the pilot.
During the opening battle sequence, there are several instances of recycled footage from Silent Running (1972). As the Cylons attack the first 'agro ship' an interior shot of one of the domes is shown. Just a few frames before an explosion is cut, Bruce Dern, in his "Silent Running" uniform, starts to walk into the shot.
The first constable (Farnes) to get killed at the beginning is played by Rance Howard, father of Ron (Opie) Howard.
Guest star Barry Nelson was leaving for England to begin shooting on The Shining (1980) when he was cast in this episode. Costume designer Jean-Pierre Dorléac had to meet him at the New York Airport where Nelson was changing planes to return to Los Angeles to size him up for his costume. On his first day of shooting, Nelson arrived at seven for a fitting and Dorléac had him on set in costume at ten.
