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

* 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.
** 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.
* HeyItsThatGuy
** Lots of ''Series/{{Ultraman}}'' cast members appear from time to time:
*** What's Arashi doing in this team? Really, did he have a twin? [[FridgeBrilliance Or maybe he and Furuhashi are alien clones?]]
*** Fuji plays Sanae, a friend of Anne's, in the controversial Episode 12.
*** In "Who are You?", Captain Muramatsu goes home from work, [[UnPerson only to find nobody recognizes him, not even his wife]]...
*** Ide rides in a submarine in "Envoy from Nonmalto".
*** Dr. Iwamoto is now at TPC (higher headquarters).
** Also, isn't the scientist in "The Lonely Earthling" [[YouLookFamiliar played by the same actor who also plays]] the [[spoiler:Robot Commander android]] in "Nightmare on the Fourth Planet", and [[spoiler:Alien Knackle's human form]] in ''Series/ReturnOfUltraman''?
** As far as suit actors go, [[Series/{{Ultraman}} Bin Furuya]] as Amagi. [[Franchise/{{Godzilla}} Haruo Nakajima]] played Yutom the robot.
** [[Series/{{Spectreman}} Kohji Uenishi]] is Series/UltraSeven. [[Series/ReturnOfUltraman Eiichi Kikuchi]] donned the suit in "The Ultra Garrison Goes West" two-parter.
** Dr. Kitamura from Episode 22 and the beginning of Episode 49 turns up as [[ChekhovsGunman that other doctor]] in ''Series/ReturnOfUltraman''
** Chief Yamaoka was played by Susumu Fujita, who appeared in many Kurosawa films such as ''Film/TheHiddenFortress''.
** [[Series/MightyJack Yamada]] played Kurata.
** [[Franchise/{{Godzilla}} Dr. Serizawa]] turned up, minus eyepatch, in the first episode.
* HeyItsThatVoice
** In the Spanish dub, Kiriyama is [[{{Film/Superman}} Clark Kent]]! Dan and Anne were [[{{Film/StarWars}} Luke Skywalker and Princess Leia]], respectively (for a while, anyway), and [[{{Series/Batman}} Robin the Boy Wonder]] was both Furuhashi and the Narrator.
** When [[spoiler:Alien Metron]] returns in ''Series/UltramanMax'', the actor who played his voice in his original appearance reprises his role, even in human form.
** Narrator Hikaru Urano was the voice actor for JamesStewart. Urano also narrated ''{{Series/Mirrorman}}''.
** When Seven returned in the 1994 video episode and henceforth, Kohji Moritsugu himself became TheNarrator.
** Agira's first appearance had him possessing Film/{{Rodan}}'s roar
* 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, 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/Ultraman}} Kemurjin]] costume with a new head.
* 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 kaiju from ''Series/UltraQ'' and ''Series/{{Ultraman}}'', 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''
