I'm not sure if anyone heard of this but I got this from a friend of mine.. Vic Mignogna (the VA of Edward Elric from Fullmetal Alchemist) as Uzumaki Naruto!
This past weekend at Anime North in Toronto Ontario, NarutoFan correspondant NamaeX was in attendance and caught up with a few big names in the anime scene including Vic Mignogna (Edward Elric in Fullmetal Alchemist, Brolly in DBZ) who has confirmed to us that he has been actively pursuing a role in the Naruto anime series, and also that Steve Blum (Spike Spiegel in Cowboy Bebop) will voice Kakashi (previously Steve Blum was only confirmed to be working as a script adaptor). According to Vic, the voice of Uzumaki Naruto in the series has also been cast, however he does not recognize the name from anything. NamaeX also had a chance to talk with Scott McNeil (DBZ's Piccolo) who confirmed the Naruto anime series is being done a in Los Angeles California studio.
The little preview of Naruto was about 1 minute long and began at about 23 minutes in to the show. Oddly the quality of the video was little better then that of a fansub, and the audio was the same as that we have seen. It would seem that all Cartoon Network did was take clips from the Japanese anime series, without any noticable voices except a few grunts, and show them on TV to boost up the hype for the Fall preview of Naruto. This makes perfect sense, seeing as how not a single one of the voice actors for English dub of Naruto has been announced. Just the sight of Naruto on TV made us giddy, until the American accented narrator tried to pronounce Naruto. It's also unfortunate how the promo sets the wrong premise for the series, making it seem as if the Ninja Academy is the main focus, also unfortunate that Hokage is known as Head Ninja. It will definately be interesting to see how things turn out in just a few short months.
