A massive write-in campaign began upon the cancellation of the original
Battlestar Galactica. Because letter writing campaigns in favor of restoring cancelled television programs were uncommon in 1979, it prompted
ABC to re-think their reasons for canceling the show. After some deliberation, they contacted
Glen A. Larson to see about reviving the series, albeit in some modified and less expensive format. Both Larson and the network felt the show needed some major change of focus to relaunch it as a spin-off, and Larson and
Donald P. Bellisario decided to set the new series five years after "
The Hand of God", the final episode of the original series. This would allow them to weed out many supporting characters who were now considered superfluous, including
Colonel Tigh and
Cassiopeia, which would bring down production costs. The only major characters to return from the original series would be
Commander Adama,
Colonel Boomer (replacing Tigh),
Apollo,
Starbuck and
Lord Baltar. Baltar was to have made atonement for betraying the Colonies to the
Cylons, and was now the President of the Council of Twelve. Upon discovering a "present-day" Earth completely unable to defend itself from the Cylons, Adama decided to just head off into deep space to lead the Cylons away from the planet, but Baltar suggested using
time travel technology to alter Earth's history so its technology would develop more rapidly up to a Colonial level. The Council votes this suggestion down, so Baltar steals a ship capable of time-travel and heads into Earth's past to carry out his plan anyway. After some deliberation, Starbuck and Apollo are sent after him to bring him back or at least undo his changes to history. Episodes would feature a new "Time Mission" every week, generally with Apollo at some different time in the past, and Starbuck flying back and forth between "Now" and "Then" to give information and support to Apollo.
ABC approved this pitch, and gave the approval to develop a pilot for the series. However,
Dirk Benedict (Starbuck in the original series) was unavailable at the time of filming.
Richard Hatch (Apollo in the original series) was sent a script for
Galactica 1980, but turned it down since he wasn't sure what his part in the series would be now that all the characters had changed. It was then decided the series would take place thirty years after the end of the original series, and that Boxey would be renamed Troy and take Apollo's role, while a character named Lt. Dillon would take over the Starbuck part. President Baltar was written out entirely, and Commander Xavier or Doctor Xavier was created to take up his role as the villain. The premise of setting the series thirty years after the original series created a
plot hole in that the original series ended with a video transmission being picked up by the
Galactica from the
Apollo Moon landing, meaning that the original series would have to have taken place sometime after 1969 by Earth's calendar. A thirty-year journey would mean that the Colonial Fleet could not have possibly reached Earth until the turn of the 21st Century rather than in 1980. After the pilot was completed, the network was unhappy with the time travel aspects of the story, which was intended to be an ongoing premise in each episode as the Colonials chased Xavier through different periods in Earth's history. They agreed to pick up the series only if the time-travel element was dropped. Larson and Bellisario reluctantly agreed, and the series instead became focused on Troy's and Dillon's attempts to protect some Colonial children on Earth. ==Cancellation==
