William Conrad (Cannon!) as the opening credits narrator.
Notable Original Music: Composer Johnny Harris composed the 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 Grand Theft Auto San Andreas, during the "Car Bounce Challenge" missionnote (Rhythm Games with lowrider cars).
The Other Darrin: 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 whiny and mercurial. Kane became honorable and dutybound.
Prop Recycling: The Earth starfighters were a draft design for the Colonial Vipers from Battlestar Galactica; 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).
