* ActorAllusion:
** RetiredBadass General Gordon, part of the RagtagBunchOfMisfits brought in to fight an invasion in the second episode, is played by Buster Crabbe -- who of course played Film/{{Flash Gordon|Serial}} in the old serials as well as the original Buck Rogers.
--->'''General Gordon:''' I've been [[LeaningOnTheFourthWall doing that sort of thing]] [blasting starfighters] [[LeaningOnTheFourthWall since before you were born]], Colonel.\\
'''Buck:''' [[OlderThanTheyLook You think so]]?\\
'''General Gordon:''' Young man, I ''know'' so.
** In the second season episode "Journey to Oasis", Mark Lenard plays [[Series/StarTrekTheOriginalSeries another]] alien {{Ambadassador}}.
** In "A Blast for Buck", Legion of Death leader Kellogg is on the long list of suspects who may have sent the deadly riddle. Appropriate as Kellogg was played by Frank Gorshin, who once played [[Series/{{Batman}} a Riddler]].

** MelBlanc as Twiki (in the first season).
** William Conrad (Cannon!) as the opening credits narrator for Season One.
** Hank Simms (Narrator/Announcer for Quinn Martin Productions shows such as ''Series/{{Cannon}}'' and ''Series/TheStreetsOfSanFrancisco'') as the opening credits narrator for Season Two.
** Olan Soule (SuperFriends Batman) as the 10-and-11 (Blackjack) computer in ''Vegas In Space''.
* NotableOriginalMusic: Composer Johnny Harris composed the [[{{Earworm}} memorably funky]] music for the band Andromeda in the episode "Space Rockers". The song was actually released as "Odyssey (Pt. 1)" and became an underground hit. Most recently, it showed up in the game ''VideoGame/GrandTheftAutoSanAndreas'', during the "Car Bounce Challenge" mission[[note]]({{Rhythm Game}}s with lowrider cars)[[/note]].
** And you can find it on one of the series' two soundtrack albums.
* TheOtherDarrin: Bob Elyea as Twiki's voice in the second season. Also, Kane was played by Henry Silva in the pilot movie and by Michael Ansara in the series proper. In both cases, the cast changes came with a personality change. Twiki became more grumpy and cantankerous. Kane became honorable and dutybound.
* PropRecycling: The Earth starfighters were a draft design for the Colonial Vipers from ''Series/{{Battlestar Galactica|Classic}}''; Buck's shuttle Ranger 3 and the stock footage of New Chicago were recycled from ''Galactica's'' "Terra" arc. At one point in the Pilot movie, a closeup of the Earth starfighter's joystick is identical to the 3-button joysticks in ''Galactica'' (later episodes use a different joystick prop).
* TheRedStapler: Erin Gray was rather flattered to learn that her role as the fearless Col. Wilma Deering was an inspiration for some female fans to join the military.
