Gantz:O, a 3D CGI anime film based off a manga a manga by renowned artist Hiroya Oku, I set to hit Japanese theaters on Oct. 14. Though only a few teasers have been released previously, a full-length trailer has recently surfaced online. From what could be deduced from the film's official trailer, Gantz:O is going to be one visually-pleasing feast.

The film, Gantz:O, primarily deals with the manga's Osaka arc, a story which is notable for its intense action sequences and its insane body count. In the manga, the Gantz team from Tokyo, which includes the main character Kato, are tasked to team up with the Gantz team from Osaka.

In the mission that is featured in the upcoming film, the Gantz teams get tasked with killing three very powerful aliens. Though the mission does not involve Kei, one of the franchise's main protagonists, it has still proven to be a fan favorite. Numerous iconic battles in the entire Gantz franchise happened in the Osaka arc, most notably, the debut of the Gantz Mech, which, as could be seen in the trailer, is expertly rendered.

Though it is quite undeniable at this point that the upcoming Gantz:O film would be a CGI masterpiece, avid fans of the manga are a bit apprehensive about the portrayal of one of the source material's most important and most massive arcs. After all, if there's anything that fans are quite unanimous about the previous Gantz movies, it is that the films have never quite captured the exact tone of the source material.

This is primarily due to the manga's themes of intense violence, gore and sex. Though the anime adaptation of the Gantz has been pretty faithful in this aspect, the films that have been released so far have opted for PG-13 violence. Doing so opened the films to more mainstream audiences, but it also disappointed the franchise's dedicated fanbase.

Hopefully, this upcoming adaptation would be able to balance its masterful CGI work with the intensity and grittiness of its manga counterpart. Otherwise, the movie would not be a Gantz title at all.
