* In RealLife, Kohji Moritsugu (Dan) and Yuriko Hishimi (Anne) are both restauranteurs.
\\

* ActingForTwo: Those twin alien girls from "The Secret of the Lake"? In human form, they were played by one actress. "They" appear together at the end of the episode.
** Kohji Moritsugu plays both Jiro Satsuma and Dan in Episode 17.
* BadExportForYou: It's nice to have it on R1, but the set itself lies and says its mono, when it's really a 5.1 remix with new sound effects, and the video is taken from basically ripping the R2s.
* BannedEpisode
** "From Another Planet With Love" was banned in the 1970s after a support group for atomic bomb survivors complained about comparisons between bomb victims and Spehl Aliens.[[note]]That's literal, by the way - the episode was actually rerun several times without incident or comment, but a third party published a set of cards that happened to describe Spehl-Seijin as "A-Bomb Survivor Spehl-Seijin" (which isn't inaccurate, but can really only invite bad-taste comparisons). Tsuburaya banned the episode outright as a result of the controversy, as well as all elements from it.[[/note]]
** In 2011, "Super Weapon R-1" was banned in Japan after the Fukushima Daiichi disaster.
* CompletelyDifferentTitle: In Mexico, it was known as ''El Agente Ultrasiete''.
* CreatorBacklash: Director Akio Jissoji always thought the scene between Dan and Alien Metron in "The Targeted Town" was silly, even when he filmed it.
* IronyAsSheIsCast: Given that Bin Furuya was a judo expert and he played the HenshinHero in the [[{{Series/Ultraman}} previous show]], it's surprising he played the NonActionGuy in this show.
* MissingEpisode: Ultra Seven is this and then some. Tsuburaya has a self-imposed ban on Episode 12. Out of the Hawaiian Dub, only episodes 21, 22, and 35 survived. In the Cinar/Turner dub, all episodes were dubbed, but between 1985 and 1994, Turner's own video copies of episodes 5, 6, and 7 disappeared. Strangely enough, the banned Episode 12 was dubbed and broadcast in the States[[note]]Spehl-Seijin is made out to be a vampire of sorts[[/note]], and can even be found online. Nowadays, "Super Weapon R-1" is banned due to parallels to the Fukushima-Daiichi disaster.
* PropRecycling: Alien Qurasso's costume is a [[Series/UltraQ Kemurjin]] costume with a new head. The Science Patrol's Mars-133 was cut down and turned into the Ultra Garrison's "Paralyzer" stun-gun.
* WhatCouldHaveBeen
** Was originally supposed to be a more hard sci-fi show similar to ''Series/LostInSpace'' called ''The Ultra Garrison'', but TBS urged a rewrite due to being too similar to rival show ''Captain Ultra'', and the show was turned into ''[[WorkingTitle Ultra Eye]]'', where Dan was supposed to transform into Redman, who was also [[SpinOffspring Ultraman Junior]]. The Capsule Monsters were supposed to be [[Series/UltraQ Peguila]], [[Series/{{Ultraman}} Antlar, and Red King]], but Tsuburaya wanted to do more with their budget, so the capsule monsters became new monsters. ''Ultra Eye'' was reworked into ''Ultra Seven'' and the rest is history.
** Among the bizarre rejected ideas, producer Masami Sueyasu proposed the series become a Japanese analog to ''Literature/AlicesAdventuresInWonderland'' combined with ''Film/TheRedBalloon'', writer Akio Jissoji proposed a series revolving around a time-traveling family and their everyday lives, Hajime Tsuburaya proposed a new season of Ultraman that basically pandered to the sponsors (think MerchandiseDriven to the Nth degree like today's Franchise/KamenRider), and Eiji proposed a cross between ''Series/{{Thunderbirds}}'' and ''Series/LostInSpace''.
** The ''Ultra Garrison'' proposal would have revolved around a team of astronauts and RobotBuddy "John", who lived in a space station called Mother and were Earth's first line of defense against alien invaders. The concept came off as too derisive, and the executives ordered Tsuburaya to rewrite it.
** In addition to Ultraman Junior, there would be both good and bad monsters, and good monsters would fight on humanity's side. ''Series/UltramanGaia'' saw this idea come to fruition.
** In one draft, Dan would have been half-R-alien (possessing ESP), half-human.
** One of Seven's preliminary costume designs looked similar to Series/UltramanMebius.
** Most of those designs lacked an Eye Slugger.
* WorkingTitle: ''Ultra Eye''
* YouLookFamiliar: Robot Commander was played by Dr. Niwa[[note]]Alien Prote in disguise[[/note]]'s actor.
