NOM NOM NOM NOM NOM!!! Godzilla loves his rare streaks.
It's amazing for a 1954 Kaiju film to have this degree of background information. Especially when this movie is based on a real-life tragedy.
Tropes for Trivia
Dawson Casting: Inverted. Akihiko Hirata was 26 at the time while his character Daisuke Serizawa is supposed to be in his 40's.
Executive Meddling: A rare case where it was a good thing. Tomoyuki Tanaka told Eiji Tsuburaya that it would take seven years to complete via stop-motion. So suitmation was the only option to make the film quicker. This became a staple in later Toho films.
Godzilla Debuted in 1956: Averted in an interesting way. This film was made in 1954, and sent to America in 1955 to the Japanese-Americans of that era to see the film, where it was later on picked up and dubbed as Godzilla: King of the Monsters. It wasn't until 2004 where it was shown theatically in the US, along with two DVD and Blu-Ray releases.
People in Rubber Suits: Godzilla was actually an interesting case where the film wasn't intended to use suits. Originally, it was going to be in stop-motion, but Tomoyuki Tanaka advised Eiji Tsuburaya that it would take 7 years to complete the film through that method. So they had 2 suits constructed. The original, superheavy 200 pound suit that couldn't be used (due to the latex increasing the weight), and a slightly lighter suit. Both Haruo Nakajima and Katzumi Tezuka still had their own problems wearing the second suit. Despite Haruo Nakajima developing blisters, he would relish the role until Godzilla vs. Gigan.
Spell My Name with an S: Godzilla's Japanese name is a result of the combination of the words "Gorilla" and "kujira" (Japanese for whale). When Godzilla was cataloged to be sent to America, his name was rendered as Godzilla (as explained in the Classic Media commentary). However, GODZILLA was declared as his official English name while Gojira remains his Japanese name. The English name would continue to be used on sequels that involved English-speaking characters, with the exception of King Kong vs. Godzilla.
Contrary to popular belief the name GODZILA was not chosen by the western distributors of the film, but by Toho's international division.
Urban Legend: the origin of Godzilla's name has long been a source of debate. There's several potential explanations:
1. There was a stagehand working at the studio whose nickname was "Gojira", purportedly due to his great size. However, given Godzilla's immense popularity, the notion of such a man remaining completely anonomyous for 60 years is improbable, to say the least.
2. Haruo Nakajima (Godzilla's suit actor) stated there was a contest among the staff to think up the name.
3. Ishiro Honda's wife believes it was randomly made up by him and Eiji Tsuburaya, and the staff working on the film often make jokes. Honestly, even we don't know. So take what you will.
What Could Have Been: Quite a few. Tomoyuki Tanaka initially described the as-yet unnamed project as a story of a monster awakened by atomic bomb testing. As the story evolved, it was named Project G (G meant Giant at this point), then later to Godzilla. During production, the movie's titular monster was to be a literal cross between a gorilla and a whale, but then decided to make the monster dinosaurian. However, artwork exists of an ape-looking thing with the head of a mushroom cloud, until the final design became the creature we know and love.
Not to mention, Akihiko Hirata was to play Ogata and Akira Takarada as Serizawa. Takarada confirmed it, and thus, the roles were tastefully switched.
Godzilla was originally going to be a giant octopus, then later a giant fire-breathing gorilla, before Toho decided to make him the radioactive dinosaur we all know and love today.
Likewise, Godzilla himself was originally going to be portrayed via stop motion animation. The idea was quickly dropped when the filmmakers realized it would be too time-consuming.
Dr. Yamane was originally going to be a full-blown Mad Scientist (wearing a cape, living in a gothic-style house, etc). The original idea was that Yamane was going to sabotage the military's efforts to kill Godzilla. But Ishiro Honda modified the character to one who wanted to Save the Villain because it survived an H-Bomb testing.
This is one of the only attempts to portray Godzilla as a carnivore (Godzilla vs. Biollante being the second) with Godzilla having a dead cow in his mouth. Tsuburaya's cameraman told him the scene was too graphic so it had to be reshot. Which defeated the purpose of making it the Horror film it already was. The other problem was a matter of scale; the filmed cow would have been unnaturally huge, and an average cow would've been too tiny to see.
