Ultra Seven is sometimes incorrectly called "Ultraman Seven" by many sources outside Japan (or in the case of KHON/Honolulu, Hawaii, Ultra7, as listed in TV Guide when it ran in 1975).

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.
It is a revival of the 1967 classic Ultra Seven, and is the first in Tsuburaya Productions' Ultra hero series to be exclusively for an adult audience and in wide screen high-definition format.
