The other day I went and watched GANTZ for the one night world premiere. I was also lucky enough to get to see Nino and Matsuyama. It is unfortunate that the movie was dubbed, however, I really like the movie. Gantz is a really great movie with wonderful actors and actresses. Because I don't read Gantz, my perspective is different about the movie than those who actually read it. Even so, I think that Yuusuke Watanabe did a wonderful job with the script and his interpretation of Gantz and Producer Sato did a great job with the movie.

Gantz Premiere Greetings

There were 2 portions of interviews, the live casting and the exclusive fan interview. I was there for both.

Afterward, I went and watched Gantz again at a different theater.Kanata's acting is really great, I just wish I could have heard his voice too.

Here's the Trailer for Gantz 2...in English, if you're curious about the English Voices...

And look, I got a reply from the script writer Yuusuke Watanabe!

"I can't say thanks enough. @ I watched Gantz last night! It's a really wonderful movie! You did a really great job with the script!
