#15: Mindy Sterling as Clarnella
Clarnella is one of the Grinch’s eccentric adoptive mothers, delivering tough love, wild energy, and plenty of comedic timing. Her frantic attempts to raise a very unusual Who create some of the movie’s funniest flashback moments. She helps shape the Grinch’s childhood in a way that’s both absurd and oddly sweet.

Before her role in the film, Mindy Sterling had already earned laughs as Frau Farbissina in the Austin Powers series. She was known for her bold comedic delivery, memorable voice, and scene-stealing presence. The Grinch gave her another chance to shine in a larger-than-life character.
