1. Gojira, Godzilla's Japanese name, is a portmanteau of the Japanese words for gorilla (gorira) and whale (kujira,) the original basis for his design.
2. Despite the Godzilla series' campy reputation, the first movie was a straightforward horror movie, as Godzilla was a clear metaphor for the atomic bomb.

6. Godzilla's iconic roar was created by rubbing a resin-coated glove up and down the strings of a contrabass.

11. A reporter character named Steve Martin, played by Raymond Burr, was added to the American adaptation of Gojira. When the character reappeared in the American adaptation Godzilla in 1985, he was only referred to as "Steve" or "Mr. Martin," because of the popularity of the comedian.
12. At the time of its release, Gojira was the most expensive Japanese film ever made.
13. There have been 30 Godzilla movies — 28 Japanese ones and two American productions.
14. The 1954 Godzilla was 50 meters tall, making him just taller than Tokyo's tallest buildings at the time. His size would increase over the years as buildings got taller.
15. The tallest Godzilla was from the recent 2014 film, where he stood 350 feet tall.
16. Godzilla is more of a gray color — not green as many people and some old posters assume. (One exception is Godzilla 2000, where he has a greenish tint to him.

23. Godzilla stared in a series of Marvel comics and fought the Avengers at one point.
24. A joke in Godzilla vs. King Ghidorah implies that Steven Spielberg's dad saw a UFO fly over an American battleship while serving in WWII, thus inspiring the director's hit movies.
25. In The Return of Godzilla, a Soviet soldier makes a heroic attempt to stop the accidental launch of a nuclear missile. The scene was recut in the American version to make the launch a deliberate act.
26. In Godzilla vs. The Smog Monster, which is possibly the weirdest film in the whole series, Godzilla flies.

28. Godzilla (1998) Director Roland Emmerich based Mayor Ebert and his aide Gene on the movie critics Roger Ebert and Gene Siskel after the duo gave his previous movies bad reviews.
29. The monster from the 1998 American Godzilla was so disliked by fans that it was nicknamed G.I.N.O. — Godzilla In Name Only.
30. Toho, the Japanese studio behind Godzilla, officially calls the American monster Zilla, and the real Godzilla defeats him in less than 20 seconds — the shortest monster fight in series history — in 2004's Godzilla: Final Wars.
31. That wasn't the first time that Toho dissed the American Godzilla. In 2001's Godzilla, Mothra, and King Ghidorah: All-Out Monsters Attack, the Japanese military references a monster in New York that the Americans thought was Godzilla, but really wasn't. Sweet burn.
