In one "Astro Boy" manga story Tezuka expressed frustration towards the restrictions passed by American television networks on the adaptation of the newly titled "Astro Boy" television series. The U.S. version did not air an episode showing a dog being operated on, as the producers believed it was too cruel and grotesque to show. Tezuka criticized this as hypocrisy, as non-Japanese eat and kill animals in manners he described as “grotesque.” Tezuka added that many white people in Africa shot animals for sport, yet people in England spread false rumors about Japanese people eating dogs.
