Continuity mistake: Godzilla noticeably changes size throughout the movie. For example, she is shown lairing in a subway tunnel, but she cannot fit into the Hyde Park tunnel (taxicab scene), which is significantly larger than a subway tunnel. Also, compare the size of Godzilla's eye next to Matthew Broderick during the fish scene and Godzilla's death scene. The eye is way bigger in the latter.
Continuity mistake: Near the end of the movie there are 3 US Navy F-18 planes. The lead plane shows a graphic of 4 missiles, 2 of which he launches at Madison Square Garden. Then later, and without landing, the 3 planes fire at Godzilla, 2 missiles from each plane on both passes. This means the lead plane fired 6 of its 4 missiles.
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: 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.
