Mighty Jack (マイティジャック Maiti Jakku) was a tokusatsu science fiction/espionage/action TV series. Created by Japanese effects wizard Eiji Tsuburaya, the show was produced by Tsuburaya Productions and was broadcast on Fuji TV from April 6, 1968 to June 29, 1968, with a total of 13 one-hour episodes. The music for the episodes was done by Isao Tomita and Kunio Miyauchi.
Reportedly, Eiji Tsuburaya considered this series his masterwork because the focus was on the people rather than on the vehicles and special effects (the show never had any monsters or aliens, as his more famous shows Ultra Q,Ultraman and Ultra Seven did.) This focus on the people was similar to the works of Gerry Anderson, of which Eiji was a big fan. The Mighty Jack mecha/HQ featured in this series also has some similarities to Eiji's previous TV masterpiece, Ultra Seven.
Even for the original series of 13 one hour-long episodes, the ratings were low. The follow-up series, Fight! Mighty Jack, fared better in the ratings, perhaps because of its inclusion of monsters and aliens rather than purely human evil-doers like Q.
The insignia of the titular heroic spy team has also become the current logo for Tsuburaya Productions.
The more comical sequel series, Fight! Mighty Jack (戦え！マイティジャックTatakae! Maiti Jakku?), aired on the same network from July 6 to December 28, 1968, with a total of 26 half-hour episodes, equalling the original in length.
The organization Mighty Jack is formed to combat the criminal syndicate known as "Q", and are given a large array of advanced weapons, chief among them being a high-tech submarine. Harold Hatari is abducted by Q, and Mighty Jack is dispatched to rescue him. Hatari is interrogated and threatened with blinding lights, but the Mighty Jack crew rescue him in the nick of time. Later, Q is discovered to be using "hot ice" (water that remains solid at room temperature) to create weapons and a secret ocean base disguised as an iceberg (though it's not precisely clear how hot ice could be a major world threat). Q then attempts to take over the Mighty Jack sub. Written by Leo L. Schwab <firstname.lastname@example.org>
