series producer  Tomoyuki Tanaka (I) (qv), who had been hospitalized during the  films production, was enraged by the film once he saw it, telling  director Yoshimitsu Banno (qv) that he had ruined the Godzilla  series. Tanaka immediately ordered the filming of a more  conventional Godzilla movie  (_Chikyû kogeki meirei: Gojira tai Gaigan (1972)_ (qv)). Thus, the  "Smog" sequel was never made.
