- Awesome Music:
- The Bert Shefter/Paul Sawtell Kronos cue used for the Osaka Castle duel in Gigantis.
- While not as catchy or memorable as his later work (Godzilla or otherwise), composer Masaru Sato still delivers on some good tracks in this movie, such as the opening title theme which doubles as the military march heard throughout the film. Simplistic, but effective.
- Contested Sequel: Being the first direct sequel of the series, the film has mixed views. Many feel that it's lost most of the atmosphere of the original film. It's still a horror film, but it doesn't possess the amount of tragedy and consequences of the original film, whereas the original has struck a lot of anvils that needed to be dropped. Others enjoy the film for having more Godzilla, more sets to show off and wreck, and doing something new by pitting Godzilla against another monster rather than just have him fight the humans. The series would continue on with King Kong vs. Godzilla as a Surprisingly Improved Sequel/Even Better Sequel
- Critical Research Failure: The whole "Origin of Gigantis with stock-footage-laden" makes no sense even after granting license for "giant fire/radiation breathing monsters".
- Hilarious in Hindsight: Warner Bros. distributed this film in the West as a double feature with Teenagers from Outer Space. They would later work with Legendary Pictures to make their own Godzilla movie.
- Doubly so, replace "Fire" with "Radiation" and the MonsterVerse kaiju have nearly an identical origin to the kaiju in the Gigantis dub.
- Macekre: Seriously, who wrote the English version? Obviously, the Japanese screenwriters didn't when they wrote the Japanese version. While Paul Schreibman gave the excuse that changing Godzilla's name to Gigantis was to avoid confusion, the English script was ridiculously bad. It's hilarious. Due to his 1999 interview, he said the original title was "Angurus". Yes, "ゴジラの逆襲" (Godzilla's Counterattack) is called "Angurus". The only positive line in the film was "It was the sight to crush the hearts of men" delivered by English Tsukioka (Keye Luke).
- So Okay, It's Average: In his review, SF Debris describes the film like this, praising it for continuing to try to tap into deeper themes, such as the effects of war and humanity's need to pick up the pieces and rebuild, as well as trying to find intelligent and credible ways to deal with the monstrous threats without reducing their menacing power. However, between the technical disaster of the monster-fighting shots and the weak execution of the themes and human drama, the film is watchable rather than great, and still a step down from its classic predecessor.
- Special Effect Failure: The prop used for overhead shots of Godzilla on the island simply stands still without even a budge. It was originally supposed to walk, but either it wouldn't work, or Tsuburaya simply thought it wasn't convincing enough.
- Rather than the standard Overcrank in kaiju films that exposes more frames per second and creates a "slow-motion" effect that gives the impression of great mass, the camera technician accidentally undercranked the monster footage, creating an effect that comes in somewhere between pseudo-Stop Motion and The Keystone Kops. There's a reason western viewers may start hearing Yakety Sax in their heads during the monster fights. Special effects guru Eiji Tsuburaya was furious, but there wasn't enough money to reshoot the relevant sections, meaning the movie effectively ruins all of its Money Making Shots
- While the JSDF is using their missile trucks to shoot at Godzilla, you can tell the people are dolls on the trucks.
- The Godzilla puppet used for closeups is heavily Off-Model compared to the suit, and the frantic jerking-around at times reveals part of the puppeteer's arm.
- So Bad, It's Good: The Gigantis cut to an extent. If one found the Japanese version boring to begin with, the hysterical cartoony dubbing and the out of place stock footage are sure to correct that.
- Stock Footage Failure: The nightclub scene includes stock footage of an actual Japanese stage show. This would be fine as far as it goes... except that the performance was very painfully obviously taken from pre-1945 propaganda footage, complete with draped Imperial Japanese, Fascist Italian and Nazi German flags. This predictably causes problems for most everybody who wants to release or air the film today. Most times, they superimpose a black or grey disc over the swastika and call it good... which invariably fails as the disc is stationary while the film has the traditional jitter.
- Visual Effects of Awesome: Despite the above, the explosion of the Osaka oil refinery and the flooding of the Osaka subway are both very impressive effects.
YMMV / Godzilla Raids Again
