Quint over at Ain't It Cool News was lucky enough to be invited into Andrew Adamson's edit suite to take a look at footage from Prince Caspian, and somehow managed to see half the film.
And he's posted some excellent scene descriptions as a result - if you want to go into the flick without knowing anything about the plot, good luck, you probably read the book when you were about five. If you did, and want to know how decent a job Eddie Izzard's made of Reepicheep, head over to AICN. If you didn't, beware of the lion-sized spoilers that lurk within the article.
