Doomed Megalopolis (OAV)

In interviews with Rintaro on the "Doomed Megalopolis: Special Edition" DVD, he implied in their interview that the story only made sense "if you've read the original novel". No translation of "Teito Monogatari" has ever been planned for release in the states.

Kyuasku Shimada was asked to provide the voice of Yasunori Kato in this anime based on the popularity of his portrayal of the same character in TOKYO: THE LAST MEGALOPOLIS and TOKYO: THE LAST WAR (the live action adaptations of TEITO MONOGATARI). This was his first time doing voiceover work for a studio.

The anime was produced as a follow to the critical and commercial success of the live action adaptation of TEITO MONOGATARI, TOKYO: THE LAST MEGALOPOLIS. TOKYO: THE LAST MEGALOPOLIS, however, was released in the US after the anime was released. Consequently many US reviewers typically accused TOKYO: THE LAST MEGALOPOLIS as being "inspired" by the anime when in reality the reverse was true. This confusion is still prevalent: in IMDB, the cover of the DOOMED MEGALOPOLIS DVD is shown for the entry for TOKYO: THE LAST MEGALOPOLIS.

Gakutensoku, the robot used to tunnel underground in the third episode, was a real creation. It was Japan's first modern robot built in the 1920's and lost in Germany. However the design of Gakutensoku in the anime was lifted from its live action counterpart in TOKYO: THE LAST MEGALOPOLIS instead of the original creation.
