Trivia / Choushinsei Flashman

• Dawson Casting: While the other actors were close to their characters' ages (some of them were even younger), Touta Tarumi was 28 when he played Jin (who is supposed to be 23).
• Multiple Languages, Same Voice Actor: A really bizarre version of this happens in the Latin American dubs (both Spanish and Brazilian Portuguese versions): The Spanish dub was done by the Brazilian voice actors who did the Portuguese dub themselves, rather than hiring native speakers for the job, and the only replacement was the narrator, which was voiced by a Puerto Rican voice actor.
• Prop Recycling: The cab of Titan Boy was originally a cancelled◊ Machine Robo toy, then got pulled out of mothballs and remolded for this show; after that, the Machine Robo: Revenge of Cronos line took the Titan Boy cab and turned it into two different characters (they were explained as being brothers to account for their similar looks); one came with a trailer, but couldn't combine with it like Titan Boy did. (For added points, one of the villainous ships was a recycled Jaguar Vulcan.)
• The Other Darrin: Eiichi Onoda plays the narrator instead of Nobuo Tanaka, who previously narrated Dengeki Sentai Changeman.
• What Could Have Been
  • A plan for a five-piece robo ran into trouble, with the Second Robo being introduced as compensation. The concept would be fulfilled in the next series.
  • Titan the Hero was originally planned to be a semi-regular character who would show up once in a while to help out the Flashman team and pilot the Great Titan. Had this been the case, Flashman would've been the first Sentai series to feature an extra hero.
