Big X


  • The original work was offered not to Mushi Production Commercial Firm but to Tokyo Movie, a newly founded animation company, as its very first work. This was the first time that one of Tezuka Osamu's original works was produced by a company other than Mushi Production. Although the original Manga incorporated serious story development involving the terror of fascism in the war against the Nazis, the storyline simplified for the animation version into one of justice prevailing over evil. In the original Manga, Big X was made more powerful when injected as a medicine. In the animation version, however, the idea pf the injection was replaced by an electromagnetic pendant, presumably in anticipation of possible objections over the visual similarity to drug abuse.
