#17: Tim Meadows as Principal Duvall
Operating as North Shore’s weary authority figure, Principal Duvall provides dry commentary on teenage behavior rather than genuine discipline. His detached humor underscores the adults’ limited control over student social structures, reinforcing the film’s satirical take on institutional power.

Prior to Mean Girls, Tim Meadows was already a well-established comedian thanks to his long tenure on Saturday Night Live. The role allowed him to bring understated absurdity to a supporting part, adding credibility and comedic weight without dominating the teen-centered narrative.
