* TheCastShowOff: Megumi Mori gets to show off her singing and musical talents in episodes 22 and 44.
* TheDanza: Megumi Mori as Megumi Misaki.
* ExecutiveMeddling: Liveman was originally supposed to be a three-member team through to the end, until the producers realized it was the tenth Super Sentai show since the franchise's revival with ''Series/BattleFeverJ'' and they wanted to do something special. Thus, Black Bison and Green Sai were added to the team mid-series. This caused some plot aberrations with previous episodes (Yusuke was unaware of Tetsuya's existence, despite becoming acquainted with Takuji's other brother Takeshi in an earlier episode). But it also led directly to the introduction of the Live Boxer and Super Live Robo, the first ''Franchise/SuperSentai'' HumongousMecha to be formed from two smaller HumongousMecha. A net positive, all in all.
* MilestoneCelebration: ''Liveman's'' run saw the first official commemoration of a ''Franchise/SuperSentai'' anniversary. As the franchise was still regarded as having started with ''Series/BattleFeverJ'' at the time[[note]]''[[Series/HimitsuSentaiGoranger Goranger]]'' and ''[[Series/JAKQDengekitai JAKQ]]'' would not be incorporated until ''[[Series/ChourikiSentaiOhranger Ohranger]]''.[[/note]], Liveman was recognised as the 10th series with a commemorative logo featuring the ''Liveman'' PowerTrio with the previous 9 Red Rangers.
* StuntDouble: A notable exception in Yutaka Hirose, who played Dr. Kemp. Hirose is a trained stunt actor and did all of his own stunts, including those as Beauty Beast Kemp and Fear Beast Kemp.
* ThoseTwoActors: Before playing teacher and student, Creator/JojiNakata and Yutaka Hirose played rivals in ''Series/ChoushinseiFlashman''.
* WhatCouldHaveBeen
** As ''Liveman'' was the 10th ''Super Sentai'' starting from ''Battle Fever J'', a special episode featuring all 10 Sentai was scheduled to be aired in the final week of February. However, due to bad weather, the shooting schedule for ''Maskman'' was delayed, so there was no room to shoot the special program, and the schedule was moved up to start "Liveman" from the last week of February. The special program of the 10 Sentai, which was ultimately a glorified ClipShow, was carried over to the first episode of ''Turboranger'' the following year.
** It was originally planned for the PowerTrio to stand alone, much like ''Sun Vulcan'', before it was decide to make ThreePlusTwo.
** The suit for Monster Obular was originally intended to be worn by Creator/YoshinoriOkamoto, only for him to end up being cast as Doctor Ashura instead.
** Guildos was originally designed with the idea that [[spoiler:he actually ''was'' an alien]]. It wasn't until after his design was finished that [[spoiler:the twist of him being a robot]] was decided upon.
