Trivia: In response to fan-backlash against this film, Toho (the Japanese company responsible for the "Godzilla" film series) decided to have some fun at the expense of the film. The film "Godzilla: Final Wars" made this movie officially canonical with the "Millennium Era" film series, by suggesting that the events of this film happened, but that it was misconstrued as a Godzilla attack by the US. To even further parody this film, the "Godzilla" from this movie appears, being rebranded "Zilla", and is killed by the Japanese Godzilla within seconds.
Trivia: Director Roland Emmerich was a massive fan of Spielberg's films. Particularly "Jurassic Park." Emmerich decided to model this film more around "Jurassic Park" than the original "Godzilla" series. (In particular the "Baby Godzilla" sequences, which features many callbacks and references to the raptor scenes from "Jurassic Park").
Trivia: The mayor is named Ebert and his assistant is named Gene. These two were parodies of two well-known movie critics: the late Gene Siskel (who died in 1999 from complication from brain surgery) and Roger Ebert. They gave bad reviews for "Stargate" (1994) and "Independence Day" (1996) which were also made by Roland Emmerich and Dean Devlin, so this is also their way of getting back at them. The actors who play them also look similar to Siskel and Ebert.
Trivia: The film was meant to be the start of a trilogy. The second film would have involved the surviving "baby Godzilla" growing up into a full-sized beast and battling an insect-like creature in Australia with an army of adolescent Godzillas that it had birthed. It also would have had an emotional attachment to Matthew Broderick, who was expected to return. The third movie would have built on the second film, and would have possibly included new versions of other Japanese "Godzilla" universe monsters. However, due to the mixed-to-negative reception of this installment and budgetary concerns, the sequels were ultimately scrapped.
