The Barbie Theory

When a show or movie has the animated main character be an actor that plays the main role in every film in order to give the viewers a sense of false reality while creating the most legendary franchise (and fandom) ever.

e.g

person1 : "this new animated movie came out where the main character turns out to be an actor and has bloopers at the end"
person2 : Oh yeah that movie uses the barbie theory to engage the viewers more.
