* Props from this show were recycled for Buck Rogers in the 25th Century (1979), which Glen A. Larson also produced.

* The classic sound of the Cylons was later incorporated to K.I.T.T. in Knight Rider (1982) (both Cylons and K.I.T.T. have only one red eye, moving side to side permanently). The sound of a Viper, when it was launched from the Galactica, was also incorporated into K.I.T.T. It sounded when Michael Knight (David Hasselhoff) activated the Turbo Boost to make the car jump.

* George Lucas and 20th Century Fox brought a lawsuit against the producers over alleged similarities with Star Wars: Episode IV - A New Hope (1977). Although Galactica was indeed re-worked from its original pilot to capitalize on the popularity of Star Wars, and it employed the same special effects team and the same concept designer, the lawsuit was eventually dismissed in 1980.

* The Cylon centurions all had to be over six feet in height, to make them more intimidating, so Glen A. Larson hired a team of out-of-work basketball players.

* Muffit Two, Boxey's "daggit" (a dog-like animal) "drone", or robot, was realized by having a trained chimpanzee inside the daggit-drone costume (which was obvious by the way that it moved). Three chimps were used during the series.

* Many of the controls used on the bridge of the Galactica were standard electronic laboratory equipment manufactured at the time by Tektronix, Incorporated. This equipment was of a mainframe design, where nineteen-inch wide racks contained test equipment components such as multi-meters, power supplies, or signal generators that slid into these racks like books on a shelf. One can notice tier after tier of these racks used all over the bridge as control panels. Tektronix was even mentioned in the closing credits as having provided "test and display equipment".

* Much of Glen A. Larson's Mormon religion is evident in the series. Such details include: The "Quorum Of The Twelve", also called the "Council Of The Twelve", which is the Mormon ruling body under the leadership of their "Prophet", the term "sealing" used for marriage, as in a Mormon Temple wedding, and the reference to "sealings" being "for all the eternities", as with Mormon "celestial" marriages being "for time and eternity". Other aspects of the Mormon religion are also apparent in every episode. The moral lessons of each episode are all Mormon in design.

* The first weekly television series budgeted at over one million dollars per episode. Unfortunately for the production, much of this lavish (for the time) sum was consumed by the visual effects. This necessitated the frequent, and often obvious, reuse of effects footage throughout the series wherever possible. Glen A. Larson ascribed this to ABC possibly having been too quick to buy the program. He had originally planned on producing it as a series of made-for-television movies.

* Dirk Benedict modelled the character of Lieutenant Starbuck on James Garner as Maverick (1957), and never liked Katee Sackhoff's character of Kara "Starbuck" Thrace in the remake, derisively calling her "Stardoe".

* The helmets of Colonial warriors were inspired in the headdresses of ancient Egyptian pharoahs. For Galactica pilots, they also featured a bird motif, a quiet homage to Star Trek creator Gene Roddenberry, who was nicknamed by cast & crew, "the Great Bird of the Galaxy".

* Respected fantasy artist Frank Frazetta was commissioned to produce four promotional paintings for the series, all of which appeared in TV Guide and various other magazines. One of the paintings (originally used for "Saga of a Star World") appeared on the cover of the Berkley novelization "Battlestar Galactica 2: The Cylon Death Machine" by Glen A. Larson and Robert Thurston, published in early 1979.

* In the opening credits, the words that start "Life here began out there", were spoken by Patrick Macnee, who provided the voice of the Imperious Leader.
