#3: Mary Frann as Joanna Loudon
Joanna Loudon brought class, warmth, and a touch of big-city sophistication to the cozy chaos of Newhart. As Dick Loudon’s elegant wife, Mary Frann played her with charm and subtle humor, turning every scene into a blend of wit and tenderness. She was the show’s grounding force amid the quirky Vermont madness.

Before landing her defining role, Frann had spent years working in soaps and TV guest spots. Her poise and beauty made her a natural leading lady, but Newhart let her show her comedic side. Audiences loved her mix of grace and good humor — the perfect foil to Bob Newhart’s understated deadpan.
