Minas Morgul is shown first in "The Fellowship of the Ring", when the Nazgûl leave the city and ride towards the Shire to pursue the One Ring. It features again when Frodo and Sam make their way towards Cirith Ungol. These sets were designed by the illustrator John Howe. All nine Nazgûl are shown riding winged monsters. Jackson's monsters explicitly differ from Tolkien's description in that they have teeth instead of beaks. The Nazgûl use them in battle more extensively than in the book. In the film the Witch-king's mount is largely responsible for the death of Théoden and his horse Snowmane, a departure from the book. As confirmed in the films' audio commentary, the design of the monsters was based largely on illustrations by John Howe.
