I went with trepidations, figuring Tilda Swinton would be wonderful and the rest would be so-so. I was delighted to be wrong. The movie really hinges on the four children, they are the center. I thought it was extremely well-cast and acted. I can't remember the actors names but Lucy is enchanting, Peter is noble, Susan is a difficult role as the practical, spoil-sport so I can't say she was marvelous, but really Edmund is where everything revolves.
This Edmund was really great. I was able to care about him and hope for him in a way I never did in the book. Kudos to the kids.
In the book, Mr. Tumnus was pivotal, even if briefly seen, and the movie's Mr. Tumnus was delightfully sweet and touching. There's a special scene between he and Lucy that is inventive and wonderful.
Aslan - impossible really to capture as he is a concept. I felt the facial expression was so true to the sense of sorrow that Aslan carries but I was not fond of Liam Neesan's voice. Somehow that did not work for me, nor did the voice of the wolf.
But Aslan does convey goodness and it's transitory nature and the end brought that home so well. While many seem to believe this is a Christian-themed movie, I think whatever you believe will work because the themes of good and evil, nobility and sacrifice are universal and symbolic.
A beautiful movie that I highly recommend to those who love adventure, fantasy and myth.
