History Trivia / BattlestarGalactica2003

* StuntCasting: Richard Hatch, who played Apollo in the original series, advocated for a sequel series for years. When the Sci-Fi series was greenlighted, a retool rather than a sequel involving him, Hatch was initially (and loudly) upset. Ron Moore won him over and Hatch was cast as Tom Zarek, one of his more memorable and well-received roles.

** Tricia Helfer initially bleached her hair platinum blonde but eventually switched to a wig as the process was damaging her hair. This actually made it easier for her to play various copies of Six who have different hairstyles such as Gina Inviere or Natalie Faust, both of whom have Helfer's natural sandy hair colour, or the raven-haired Six in [[Recap/BattlestarGalactica2003S03E06Torn "Torn"]].
** Jamie Bamber dyed ''his'' sandy hair darker so he'd look more like Edward James Olmos. Olmos also wore blue lenses to increase the resemblance between them.

** Jamie Bamber, who plays Lee/Apollo, is British (though his father is American and he claims to have been raised partly in Detroit). Most of the cast, though, are Canadians, so they sound almost like Americans. However, Canadian English still occasionally creeps in, such as with Tricia Helfer's pronunciation of "resources" as "ree-zources."

** At the end of "Final Cut", Lucy Lawless, who otherwise used her natural Kiwi accent, affected a Canadian/American accent for the Number Three in the cinema.

** In full effect with Lee Adama, whose actor isn't Latino while Creator/EdwardJamesOlmos, who plays his father, is. HandWaved slightly as Adama's late wife is played by a white actress and Ellen Tigh says that Lee looks like her. Also, Jamie Bamber dyed his naturally sandy hair brown and EJO wore blue contact lenses so that they would look more alike.

* TheCastShowoff: Gaeta singing in the infirmary. Alessandro Juliani is a trained opera singer with a Bachelor's degree in it, as well as having worked with the Vancouver Opera and singing his own parts in other roles.

* TheWikiRule: There's the Battlestar Wiki, which can be found [[https://en.battlestarwikiclone.org/wiki/Main_Page here]].

** There's also the Season 1 episode [[http://en.battlestarwiki.org/wiki/Litmus "Litmus"]] and TNG's [[http://en.memory-alpha.org/wiki/The_Drumhead_(episode) "The Drumhead"]] both involve an explosion occurring aboard the ship, and a female officer being assigned to head up an investigation, only to start going crazy and accusing everyone in sight of being a collaborator, finally ending with her accusing the ship's commanding officer. Unlike the above two, though, this episode isn't exactly hated.

* McLeaned:
** Billy Keikeya's actor Paul Campbell wasn't under contract and was constantly unsure whether he wanted to stay on the show, preventing his character from being involved in any significant plot arcs. The writers eventually got fed up with this and killed off his character. Unfortunately, because the build-up of the third leg in the LoveTriangle, involving Dee and Apollo, kept ending up as deleted scenes, this came across to many viewers as an especially abrupt MurderTheHypotenuse in favor of the pretty boy over the awkward geek; with Dee dumping him out of nowhere and suddenly jumping into a relationship with Apollo all in the same episode where Billy got shot (perhaps marking the beginning of the HateDom which grew for Dee's character).
** While at the time it was unclear whether Cally's death was the writers' idea or whether Nicki Clyne had wanted to leave the show, it emerged years later that Clyne had asked that Cally be killed off so that she could devote more time to her membership of the NXIVM cult.

* ContractualImmortality: Commander Adama is not going to die. After beating a superhuman replicant to death with a flashlight in the miniseries, he's pretty much indestructible, and Edward James Olmos is also the highest billed actor in the entire series.

** Creator/GracePark originally tried out for first Dee and then Starbuck, before Kandyse [=McClure=] and Creator/KateeSackhoff got the parts and she was cast as Boomer. The producers were so impressed by her Dee audition that they let her try out for Starbuck, and she was one of two finalists for the role. Subsequently, she didn't need to read for the role of Boomer, and, thinking it was a minor role, got a pleasant surprise when she read the end of the Miniseries and learned her character was a Cylon and a major role.

* DeletedScene: [[invoked]] Many, from many episodes. They were [[WordOfGod still considered canon by the show runners]], even to the point of being referenced in PreviouslyOn montages as if they ''had'' appeared in episodes. Depending on the viewer, this either makes the show BetterOnDVD or just plain confusing.

** Olmos's wife Lymari Nadal appears briefly in the Miniseries as a woman asking about the status of her husband after the Cylon Attack. She makes a surprise return after seven real-world years in the post-series movie ''[[Recap/BattlestarGalactica2003ThePlan The Plan]]'', where her character is expanded on: her name is Giana O'Neill, she joins the deck crew, and her husband is actually one of the Simon-model Cylons.

** Brendan "Hot Dog" Costanza, one of the pilots first introduced in "Act of Contrition", is played by Bodie Olmos, son of Edward James Olmos. In the "Last Frakkin' Special" aired before the finale Bodie mentions how much he enjoyed the opportunity to work with his father.

** Ryan Robbins, who plays the officer that gets blown up along with Armistice Station in the opening scene of the Miniseries, later reappears in Seasons 3 and 4 as Charlie Connor. He was only on screen as the Armistice Officer for less than five minutes and was under heavy age-enhancing stipple makeup, making him barely recognizable.
** John Mann, who played ''Galactica'''s original CAG turns up as a hustler in "Black Market", only for his scenes to have been cut from the aired version of the episode.

* TheProducerThinksOfEverything: The ending, where [[spoiler: the colonials find ancient Earth and abandon their technology, framing the entire story as an origin for mankind]] was in the series bible from before the first season even began.

** Kerry Norton who plays Layne Ishay, one of the medics in Galactica's sickbay, is married to Jamie Bamber who plays Apollo.
