<Li> Pablo Adán as Narrator / Voice of Faun </Li> <P> The idea for Pan's Labyrinth came from Guillermo del Toro's notebooks, which he says are filled with "doodles, ideas, drawings and plot bits". He had been keeping these notebooks for twenty years . At one point during production, he left the notebook in a taxi in London and was distraught, but the cabbie returned it to him two days later . Though he originally wrote a story about a pregnant woman who falls in love with a faun, Sergi López said that del Toro described the final version of the plot a year and a half before filming . Lopez said that "for two hours and a half he explained to me all the movie, but with all the details, it was incredible, and when he finished I said,' You have a script?' He said,' No, nothing is written"'. López agreed to act in the movie and received the script one year later; he said that "it was exactly the same, it was incredible . In his little head he had all the history with a lot of little detail, a lot of characters, like now when you look at the movie, it was exactly what he had in his head". </P> <P> Del Toro got the idea of the faun from childhood experiences with "lucid dreaming". He stated on The Charlie Rose Show that every midnight, he would wake up, and a faun would gradually step out from behind the grandfather's clock . Originally, the faun was supposed to be a classic half - man, half - goat faun fraught with beauty . But in the end, the faun was altered into a goat - faced creature almost completely made out of earth, moss, vines, and tree bark . He became a mysterious, semi-suspicious relic who gave both the impression of trustworthiness and many signs that warn someone to never confide in him at all . </P> <P> Del Toro has said the film has strong connections in theme to The Devil's Backbone and should be seen as an informal sequel dealing with some of the issues raised there . Fernando Tielve and Íñigo Garcés, who played the protagonists of The Devil's Backbone, make cameo appearances as unnamed guerrilla soldiers in Pan's Labyrinth . Some of the other works he drew on for inspiration include Lewis Carroll's Alice books, Jorge Luis Borges' Ficciones, Arthur Machen's The Great God Pan and The White People, Lord Dunsany's The Blessing of Pan, Algernon Blackwood's Pan's Garden and Francisco Goya's works . In 2004, del Toro said: "Pan is an original story . Some of my favourite writers (Borges, Blackwood, Machen, Dunsany) have explored the figure of the god Pan and the symbol of the labyrinth . These are things that I find very compelling and I am trying to mix them and play with them ." It was also influenced by the illustrations of Arthur Rackham . </P>
