My whole theory about why I couldn’t find any creators who realized they were leaving out female characters is because they were raised on the same ratio. I just heard someone the other day call it either ‘smurfing’ a movie, which is when there’s one female character, or ‘minioning’ a movie, which is when there’s no female characters.
We all know the huge problem there is with entertainment in general leaving out women. Especially as actors, we know there are fewer great parts for women.
The creators of kids' media had no idea they were leaving out that many female characters. They were in utter shock that the worlds they were creating were so bereft of female presences.
