Planzet is set to open this year in Japan, and it's somewhat anticipated due to its pedigree: it's being directed by Jun Awazu, who has made a career for about 10 years of doing CG animation for a wide variety of films, both anime (like Zoids Shinseiki/Zero) and live-action (Kamen Rider 555), as well as some games (2002's Shinobi). His last directorial credit, however, was a tokusatsu film called Negadon: The Monster from Mars, which featured many references to earlier Japanese films.
Today anime!anime! reports that Mamoru Miyano, best known for playing leads such as Death Note's Light Yagami, Gundam 00's Setsuna F. Seiei, and Ouran High School Host Club's Tamaki, will be playing the protagonist in Planzet, whose name is Taishi Akashima.
Joining him as his little sister Koyomi is Happy! Style member Kaori Ishihara in what looks to be her first voice-acting role ever, which should be interesting.
All in all, looks like it could be a cool film. Check out the trailer and tell me what you think.
