C.S. Lewis was not at all sanguine about a live-action Narnia adaptation, according to this letter to a BBC producer — though, unlike the framing prose in the BoingBoing post this is quoted in, his 1959 objections seem a bit more technical than philosophical.
As things worked out, I wasn’t free to hear a single instalment of our serial [The Magician’s Nephew] except the first. What I did hear, I approved. I shd. be glad for the series to be given abroad. But I am absolutely opposed – adamant isn’t in it! – to a TV version. Anthropomorphic animals, when taken out of narrative into actual visibility, always turn into buffoonery or nightmare. At least, with photography. Cartoons (if only Disney did not combine so much vulgarity with his genius!) wld. be another matter. A human, pantomime, Aslan wld. be to me blasphemy.
To that end, actually, the new film ought to be less objectionable than, say, the previous BBC live action series, which featured much clumsier puppetry for Aslan, though it’s still charming in my opinion). But bear in mind that Lewis died in 1963 — the CG capabilities available today have the potential to render Aslan et al. as something that partakes neither of “buffoonery or nightmare,” and far removed from someone dressed in a lion’s suit (which would smack enough of pagan ritual to seem blasphemous to someone like Lewis).
Given what BBC TV productions looked like in 1959 (or even 1969), I can’t say as I blame him for his concerns.
That all said, the movie may very well suck. While Walt Disney is no longer present at the helm of his company (having died in 1966), and it’s not clear what “vulgarity” Lewis is objecting to, the present company may certainly make something that is not true to the spirit of the writer. Heck, Peter Jackson approached LotR with near-reverence, and there will still folks (including in the Tolkien estate) who frothed at the mouth over his changes. It’s easy to believe that a company that’s taken such liberties with properties such as The Little Mermaid or Pocahontas or The Hunchback of Notre Dame (not to mention Kimba the White Lion) might easily screw up Narnia.
But, by the same token, that’s a battle for the fans of the work, not something to rely overly much on the 50-year-old opinions of the original author. Even someone such as C.S. Lewis.
