Did You Know?


Godzilla's famous/infamous "victory dance" after defeating King Ghidorah on Planet X was based upon the "shê" gag pose, a trademark of the mischievous character Iyami from the manga "Osomatsu-kun," created by famous Japanese cartoonist Fujio Akatsuka. Iyami would go into this pose every time he is surprised, and scream "shê!" This has become a famous pose in Japanese popular culture. Yoshio Tsuchiya (the actor playing the Controller of Planet X) was a big fan of the "Osomatsu-kun" comic-strip, and asked special effects director Eiji Tsuburaya if Godzilla could do a "shê" pose. Having already given Godzilla a more humorous and playful side, Eiji agreed, cleverly incorporating the pose into a "victory dance" for the monster. However, director Ishirô Honda was not impressed. After some debating, it was ultimately left in the final print. See more »

An undervalued gem.
15 June 1999 | by See all my reviews

A lot of 'professional' film critics seem to have an irrational dislike of Godzilla films. True, the special effects in them aren't usually fantastic but they're certainly a lot better than many 60's western dinosaur films which just rely on lizards with fins and spikes blu-tacked to them.

This film, for example, is an excellent piece of sci-fi, imaginative, well-paced and containing genuine characters and interesting monsters. An alien race want to borrow Godzilla and Rodan to stop Ghidorah attacking their home planet, but it soon turns out they are not as friendly as they seem.

One of the best Godzilla films I've seen, a true classic from the golden age of monster movies.
