First Prescreening of Prince Caspian?

Member ’nettiebelle12’ over on IMDb posted that she has seen the first screening of ’Prince Caspian.’ She writes “Last night was the first ever screening for Prince Caspian. The special effects are far from complete, but it is a brilliant movie. I might think it better than the Lion Witch and the Wardrobe.” The first known prescreening for ’The Lion, the Witch and the Wardrobe’ occurred three months before the movie’s debut so it is likely that this story is accurate.
