Red-headed child actress Liliana Mumy is the daughter of Bill Mumy, the former child star best known as the pint-sized Will Robinson on the popular science fiction television series "Lost in Space. " She and her brother Seth followed in their father's footsteps at an early age, but Liliana's introduction to acting came via voice work, overdubbing the Japanese animated comedy " Hôhokekyo tonari no Yamada-kun," which was renamed "My Neighbors the Yamadas" for American audiences. In short order, the sprightly little ingénue landed a string of one-off roles in television that led to supporting roles in major motion pictures. In the zany holiday sequel "The Santa Clause 2," Mumy played Lucy, the half-sister and precocious predecessor of the first film's Charlie, a role she'd reprise in "The Santa Clause 3: The Escape Clause." In 2003 she signed on to another family-friendly franchise, playing one of 12 kids in the Steve Martin comedy "Cheaper by the Dozen" and later "Cheaper by the Dozen 2." As she grew, Mumy began balancing her film appearances with recurring TV roles, as both an actress and a voice artist. While likely best recognized for her family films, Mumy has breathed life into a memorable animated character who shares her red hair, Myrtle Edmonds, the bespectacled tormenter of Lilo in the spin-off movies and series of the popular Disney alien adventure, "Lilo & Stitch." In 2007, Mumy landed a recurring role voicing the character Panini on the animated comedy "Chowder."
