I agree. I finally got around to making an Astro Boy page since you posted this. I've only read the manga and never got a chance to see the anime. I remember seeing images when I was younger but never had access to seeing it and always wanted to. I think the movie could do well. At least in America it has some famous actors doing the voice roles. It's also being made by the studio that put out the recent TMNT and the upcoming GATCHAMAN (which I'm dying to see).
I`ve been a robo/mecha fan for awhile so naturaly i`ve seen every Astro Boy series ever made but the manga is pretty much impossble to get here in Holland. Still a new movie about it would be a dream come true him being one of the first robo heroes around next to Tetsujin 28 who had a movie too BTW :)
