Astro Boy Flies Again
"The physics of flight because how do you test that? He's got rocket boots so perhaps it wasn't that challenging but we had to just figure out how to work within the laws of physics. There's a great scene when he just learns to fly. He's falling from the roof and falling and falling and falling and he gets up and the boots turn on and he's dumbfounded. And there's a long shot of him starting to figure it out. It's really well animated and we're happy the way it turned out."
In other words, it's pure Astro Boy.
