One of the main reasons why the series is so different from the movie it's spun off from, Godzilla (1998), is that almost all of the production crew were big fans of the original Japanese Godzilla films. Since the American movie's exact details were kept secret, down to the capabilities of Godzilla himself, the cartoon staff had no choice but to base their work on the Japanese movies. Thus, Godzilla Jr. is more anthropomorphic, has the iconic atomic breath weapon, stands more upright and does battle with other monsters.
Though most Godzilla fans are not fond of Godzilla (1998) many do consider this series to be very good and much more worthy to bear the title 'Godzilla'.
The 3-part episodes of "Monster Wars" was a direct homage to the Godzilla film Destroy All Monsters (1968).
The series was highly popular in Serbia, where it was one of the few American animated series to receive a full dub. Ironically, the Godzilla franchise itself is very unpopular in the country.
The episode of DeadLoch (1999) marked the final role for Roddy McDowall who died a few weeks after completing the episode.
