Although the series was popular for a year, Tezuka became dissatisfied with the adaptation, saying that it was too far removed from the image of the original work, and this became the driving force behind the production of
the first Astro Boy anime a few years later. In addition, when Sōji Ushio approached Tezuka in 1965 to make a live-action
Ambassador Magma, Tezuka initially suggested that he make a live-action
Big X for this reason. However,
P Productions' live-action
Magma received high praise from Tezuka, and the bad impression of live-action adaptations was dispelled, and Tezuka himself considered producing a live-action version of
Mighty Atom in 1972. ==References==
