Tezuka did that kind of self referencing alot. Evan in his anime. In the 60's episode Cobalt, Astro narrates the intro to the story in front of a live action background of the Mushi Productions studio, and during the fight scene between Cobalt and some monster bots, the characters go outside the frame of the film and then go back in again. I love Tezuka's since of humor.
Funny things include: The noses poking through the video screens, the opening of doors to step out of clouds of smoke, and the holes in Dr. O's nose when arguing w/ Duke Red's character.
