#33: Nicolette Scorsese as Mary
Mary is the flirtatious, quick-witted saleswoman who accidentally becomes the star of one of Clark’s most awkward holiday moments. Her playful charm and Clark’s nervous rambling create one of the movie’s funniest shopping scenes. She adds a touch of lighthearted mischief that fans still quote decades later.
At the time she joined the film, Nicolette Scorsese was working her way through modeling and small acting roles. She was gaining visibility with commercial work and TV appearances, and Christmas Vacation became one of her most memorable early credits. Her charisma helped her stand out in a brief but iconic role.
