The Chronicles of Narnia is a series of films based on the books in The Chronicles of Narnia series- which were written by the famous author C. S. Lewis. As yet (2012), only three out of the seven books have been made into films:
Movies Based On The Chronicles of Narnia
The Lion, The Witch and the Wardrobe (2005): It is difficult to name only one protagonist for this film. One could argue that Aslan the lion is the main character, as he can be seen as an allegorical representation of Jesus. However, C. S. Lewis dismissed that idea, choosing the term 'suppositional incarnation' instead. Other possible main characters include the four Pevensie children: The brothers and sisters Peter, Susan, Edmund and Lucy. The antagonist in both novel and film is Jadis, the White Witch.
Prince Caspian (2008): Prince Caspian himself is perhaps the main character of this particular Narnia story, although all the four Pevensie children from the previous movie also feature heavily in the film. This time, the antagonist is Prince Caspian's evil uncle, King Miraz.
The Voyage of the Dawn Treader (2010): In this movie, Brother and Sister Edmund and Lucy Pevensie (familiar from the the previous two films) return to Narnia, this time accompanied by their cousin Eustace. Prince Caspian (now King Caspian) also features heavily, with Aslan also making various appearances.
The Magician's Nephew, (which is actually the first book in The Chronicles of Narnia series of novels), is intended to be the next movie in the film series, instead of The Silver Chair as might have been expected were the films to follow the sequence of the books themselves. However, this film is not yet in development, and is not expected until at least 2014.
