O'Hara has served as a voice artist in a number of animated films, including The Nightmare Before Christmas (1993), Bartok the Magnificent (1999), Chicken Little (2005), Over the Hedge (2006), Monster House (2006), Brother Bear 2 (2006), Where the Wild Things Are (2009), Frankenweenie (2012), The Addams Family (2019), Extinct (2021), Elemental (2023), and The Wild Robot (2024).
