A towering bear named Ernest befriends a tiny mouse named Celestine in this gentle adaptation of the beloved children's book by author Gabrielle Vincent
. Celestine (voice of Mackenzie Foy) is an orphaned mouse who lives underground. An artist at heart, Celestine is training to become a dentist when she meets cantankerous bear Ernest (voice of Forest Whitaker), who has emerged from his remote woodland cottage in search of food, and nearly becomes his breakfast. Instead of being frightened by Ernest like most mice, however, Celestine strikes up a friendship with the misunderstood giant. Before long Ernest and Celestine are inseparable, but can their friendship last in a world where mice have been taught to fear bears, and bears have been taught never to play with their food? Lauren Bacall, Paul Giamatti, William H. Macy, Megan Mullally, Nick Offerman, and Jeffrey Wright also lend their voices to this traditionally animated children's fantasy that was nominated for Best Animated Feature at the 2014 Academy Awards.
