Gantz:O is a 3D live-action film adaptation based on the hit Manga & Anime by the name of Gantz. The Japanese film animation uses Hollywood live motion tracking suits as well as raw 3D animation to develop its scenes within the movies and explores multiple ranges of character animation, ranging from realistic, to exaggerated cartoon style as well as fantasy-type movement.
A form of good animation within the 12 principles of animation is to be able to apply a vast range of animation styles into one with a seamless transition that does not become an eyesore to the viewer. There are multiple fight scenes and travel scenes that you can see have fluid animation that show that a well-thought-out process has been done to achieve this effect. Gantz:O may not be of Disney, Pixar or Dreamworks standard, but the Japanese animation has developed a way of staying within these 12 principles of animation previously mentioned and distorting them to a point where different creatures have different animation styles.
An example of blending multiple styles of animation and movement together can be the classic ‘Who Framed Rodger Rabbit’ from 1988, blending real live-action with animation for an effect that makes the cartoon animation feel as if it has ventured into the real world. Although Gantz:O does not necessarily cross the real with the fake, we have a sense of realism within human-based characters due to the motion-tracked animation providing natural movement. However, the cross between animation is felt when we see fictitious monsters that break the boundaries of reality enter the film, and bring their own idea of the 12 principles.
