Trivia / Chikyuu Sentai Fiveman

• Dawson Casting: All of the main actors were roughly the same age as their characters except for Ryohei Kobayashi (Fumiya, the youngest of the siblings), who was actually the second oldest in the main cast next to Toshiya Fuji (Gaku) and six years older than his on-screen twin/real-life wife Keiko Hayase (Remi).
• Development Hell: A Region One DVD set was teased by Bruno from MMPRToys for Shout! Factory in 2019 as their second licensed pre-Zyuranger release. For a while said set had yet to see the light of day, due to Hasbro's acquisition of the Power Rangers franchise and the international rights to Super Sentai as a result. It was finally announced for a September 2022 release, presumably due to having the distribution rights renegotiated.
• Franchise Killer: Despite the rumor that it was Chouriki Sentai Ohranger that nearly killed off Sentai, this season is the one that nearly caused the franchise to end, due to low ratings AND very low toy sales (likely because seemingly all the toys for this series were badly designed and shoddily made - one Five Blaster toy yellowed despite being put in storage for a year after having been opened once)^note although other shows have had lower ratings since then, it's worth noting that in those cases, said ratings were usually offset by toy sales; Ohranger, which had ratings of 4.452% in comparison to Fiveman's ratings of 6.49%, had some of the best toy sales in the entire franchise, selling 15.9 billion yen; although we don't know the toy sales numbers for all the pre-Jetman series, it can be assumed that they were lower than those of Mirai Sentai Timeranger or Shuriken Sentai Ninninger, which sold 4 billion yen and 5.4 billion yen worth of toys respectively, if only due to the fact that Toei didn't consider canceling Sentai after those shows. There were reports of Japanese toy stores having scores of unsold Max Magma toys. Fortunately subverted when Toei decided to give the franchise one more season - and the next series ended up saving the franchise.
• The Other Darrin: Eiichi Onoda succeeded Nobuo Tanaka as the show's narrator.
• Prop Recycling: The helmet used for this series' GingaPink was taken from Immortality Bouma from the prior series, Kousoku Sentai Turboranger. The aliens' species and homeworld was given a similar name to the Bouma as a Development Gag.
• Romance on the Set: Ryohei Kobayashi and Keiko Hayase, who played the twins Fumiya and Remi, dated on the show and later married in real life.
• What Could Have Been
  • Ryohei Kobayashi was given the role of Fumiya as compensation after he auditioned for an unmade follow-up to Kamen Rider BLACK RX.
  • There was a plan that Ken (FiveBlue) would not be blood related to the other Fiveman, and in fact was meant to be revealed as Empress Meadow's son instead and the actors were even informed of this, but it was ultimately dropped because producers at Toei found the plot too dark for the show.
  • Producer Takeyuki Suzuki objected to the introduction of the Five-kun Dolls.
