* DawsonCasting: 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).
* WhatCouldHaveBeen: 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 [[SixthRanger extra hero]].
