#19: William Hickey as Uncle Lewis
Uncle Lewis brings his own brand of cantankerous humor to the film, delivering blunt one-liners and unfiltered comments with perfect timing. His grouchy presence, combined with a hint of underlying affection, adds another comedic layer to the Griswold family gatherings. He helps embody the chaos of big family holidays.

Earlier in his life, William Hickey had built a respected career as a character actor and acting teacher. He was known for his distinctive voice and memorable roles on stage and screen. By the late ’80s, he had already developed a loyal following for his quirky, scene-stealing performances.
