Part man, part-goat and part-tree, Pan, the ethereal faun, played by Jones, is at the heart of del Toro’s dark fantasy. It’s Pan who tells Ofelia, the protagonist of the film, that she is a princess in the Underworld, and assigns her the tasks in order to return to the magical world. A creature mined from the myths, Pan has an ambiguity about him — menacing and kind, wise and dangerous, he is like nature itself, with all its brutality and beauty.
