Hillari Kimble, the school bully, waltzes up to Stargirl during the dance-line, exclaims that Stargirl ruins everything, then slaps her face.

In the book, a classmate named Hillari Kimble confronts Stargirl and slaps her face during a school dance as a result of one of those actions, but the film slightly tones down the interaction.

The movie combines Hillari’s distrust of Stargirl with one of her good deeds. In the book, the boy whose bike Stargirl returns is not Hillari’s brother and it’s not that big of a deal.
