What Ever Happened to the Cast of The Grinch?

Betty Lou Who is the spirited, competitive, decoration-obsessed mom who turns holiday cheer into a full-contact sport. Her frantic determination to outshine the neighbors brings big laughs, and her bubbly personality adds energy to every scene. She perfectly captures the lovable intensity of a parent who lives for Christmas.

Before filming, Molly Shannon was a standout performer on Saturday Night Live, where she created some of the show’s most memorable characters. Her comedic fearlessness and high-energy style made her a natural fit for Whoville’s over-the-top world, and the movie tapped into her already booming popularity.
