When C.S. Lewis' famed book series "The Chronicles of Narnia" were popularized into films, Christians of the West celebrated shallowly. In fact, when did they never? Whenever any hollywood films with hero sacrificing element emerged. Of course, those who have addicted to the vanity of hollywood would find something they could indentify with as "special".
So, when Liam Neeson, the voice of the Lion Aslan said Aslan could also be Muhammed or Buddha, contrary to Lewis' original intent for Christ, unlike others, I am not surprised. No, it is not because this is just a movie or a story, but because this is how far Christians today have betrayed their Christ. And by Christians I mean not Liam Neeson but those who do not study theology, those who think they have more love than God but hypocritically show on the surface how humble they are, those Ameristians.
In the Voyage of the Down Treader, Aslan's true identity is revealed yet even closer by C.S. Lewis, portrayed in the movie Chronicles of Narnia:
Aslan: I shall be watching you always
Lucy: How?
Aslan: In your world, I have another name. You must learn to know me by it. That was the very reason you were brought to Narnia. That by knowing me here for a little you may know me better there.
Walter Hooper, a trustee of Lewis' estate puts it well for Lewis' name: "He wrote that [the whole Narnian story is about Christ]. Lewis could not have been clearer".
Although I would not dwell too much in this fantasy, I shall remember Joy Davidman's correspondence with Lewis in the movie Shadowlands telling him how she wondered if Narnia is a place Lewis is trying to escape to...
