For a sequence that showed the Cylons attacking Earth, the producers used footage from Earthquake and superimposed Cylon fighters firing and causing the destruction in the sequence. Thus they managed to create a spectacular sequence on a tiny budget.
Lorne Greene (Adama) and Herbert Jefferson Jr. (Boomer) are the only regular cast members from the original Battlestar Galactica to appear in this sequel series. As a last ditch effort to raise ratings, the producers brought back Dirk Benedict as Starbuck for one episode.
At the end of several episodes a message appeared on the screen that said: "The United States Air Force stopped investigating UFOs in 1969. After 22 years they found no evidence of extra-terrestrially visits and no threat to national security."
