AstroBoy Online Forums

For what I saw it's a pilot for the 2003 series:

All the characters have a different look than the final version.
Note Pluto and the little girl from episode 5 (she kissed Atom at 1:38, lol).
Check Atlas at 2:04, he looked like Elecman Exe, lol.
Note the face of Tobio in the photo at 3:24.
Also, note Blue Knight's metalic face.

That is 9 years old! I had not noted the different character designs except for the girl.

I've seen the english one of this.
you should hear Dr Elefun's voicein that one! =)
things I noticed were that the docters robes are different and Astro's joints are more visible.

I have hardly never seen the 2003 version(I watched it when I was six,but I have forgotten what I saw),actually I prefer the manga and the 1980 version.But I recognize that the 2003 version is the most exquisite

The first Astro Boy I ever saw was the 2003 cartoon,
so I'm kinda attached to it.
I think I prefer the style the producers decided on to this one though.

Oh yeah, I really like this trailer, the music in it is great. I only wish I knew who was voicing Astro in the english one, it's always sounded like Mona Marshall, but I've never gotten any clarification on that.
