In the movie, Elsa begins to mess with Jojo (Roman Griffin Davis) by playing into his outrageous ideas about Jews having horns, wings, and magical powers, and, in those moments, you can see shades of Caplan and Ryder. When she snaps back at him after seeing his drawings what of his young, misguided brain actually thinks about the world, you can almost hear the tone of Mean Girls' Janis Ian sarcastically explaining why she went after Regina George in the first place ("I guess it's because I have a big, lesbian crush on you!"). Later, when Elsa stands up to the Gestapo officer (Stephen Merchant) while claiming to be Jojo's sister, shades of a former queen bee, perhaps like one Regina George, could reasonably account for the confidence the young girl exudes in the face of sheer terror.
