Ladyhawke (1985)

In 12th-century Italy, the malevolent Bishop of Aquila curses star-crossed lovers Isabeau and Etienne. By day, Isabeau is a hawk; by night, Etienne is a grey wolf. Forever united but eternally separated, they find an ally in Phillipe Gaston, "The Mouse," the sole escapee from Aquila's fortress. As love becomes both balm and poison, Philippe navigates peril to help the cursed couple break free.
