Fritz Stahlbaum is a character who makes an appearance in The Nutcracker and the Four Realms movie. He is Louise and Clara's younger brother. He was portrayed by Tom Sweet. He initially appeared to be observing Clara's experiment with a device that can trap any mouse that tries to enter. He receives some toy soldiers from his late mother, Marie, when he and Clara go downstairs to meet their father, Benjamin. Fritz and Louise watch the couple dancing to the music Marie used to enjoy before she passed away, and they smile when Clara later returns home and joyfully reunites with Benjamin. Together with the other partygoers, the Stahlbaum family dances to the waltz at home.
