In the most overtly allegorical of C.S. Lewis' NARNIA series, the heroes battle the demons inside rather than white witches or evil kings. While director Michael Apted never mentions any one religion, the Christian undertones of this installment are more apparent than any of the other films. Vanity, jealousy, greed and pride are the villains here.
Lucy (Georgie Henley) and Edmund (Skandar Keynes) dream of returning to Narnia where they were a queen and king. In England, they are stuck as simple teens living with their aunt and uncle during World War II. Instead of battling mythical creatures, they're stuck fighting with their stuffy cousin Eustace (Will Poulter, SON OF RAMBOW). Then one day a painting in their room comes to life and transports them back to Narnia and onto the sailing vessel of King Caspian (Ben Barnes). At first they are unsure why they have been called back, but soon learn of the evil pull of Dark Island, which has been trapping people in its seductive green mist.
During the course of their adventure, the heroes will encounter slave traders, dufflepuds, dragons, magic ponds and a giant sea serpent that makes CLASH OF THE TITANS' Kraken look like a sea slug. Along the way, the evil mist will play on the characters' weaknesses. Lucy wishes she were as beautiful as her older sister Susan (Anna Popplewell). Edmund continues to struggle with feeling like a second wheel, only this time it's not to his older brother Peter (William Moseley), but to the new king Caspian. Eustace is susceptible to… well… just name the sin. The obnoxiously practical young man is mentored by the brave warrior mouse Reepicheep (Simon Pegg, SHAUN OF THE DEAD).
