I didnt see this mentioned anywhere, and its somewhat recent info. But if it is, remove the thread I suppose...

So their planning on making 2 Gantz movies. There related, they just have so much to work with so they split the stuff in 2 movies. Good call. They got a budget of 4 billion yen (about US$45 million).
The site for the movie (If u can read it) is: http://yj.shueisha.co.jp/gantzspecial/

As of now the only actors mentioned (that I know of) are:
Kurono - Kazunari Ninomiya - http://i340.photobucket.com/albums/o323/LuckyLuckyClover/Ka zunariNinomiya.jpg

Im mostly wondering what people think on the character cast? Is there any one out there whom you think would be a better choice?
For my part, seems like it wont be a cheap movie(s), and I just hope its a succes enough so they start making more high-quality Seinen manga adaptations.

Ah, a trailer for the first movie was released.

Looks decent, suits and special effects look good. actors seem to resemble the manga characters.

Overall im really looking forward to it, hope its a success~

Its a little old news but im sure this will be new to a few people. i for one am definitly excited for the Gantz movies. i didnt like the anime @ all but i really really really love the manga. maybe because the english voice actores are horrible imo.

The trailer was pretty LQ, and awkwardly edited, but it looks better than I expected.

Wow, this looks awesome. Thank God the U.S. didn't decide to take this and make it into an American-version live-action film....

im afraid this will turn into a Devilman kind of movie
[i liked the devilman live action
but it could have been better]

i get the same feeling from this trailer as i did when i watched the devilman trailer[2004 OMG its so long ago allready]

i hope im wrong
and this turns out to be really good

[Gantz deserves it after that piece of .... anime]
