C.S. Lewis Opposed Live Action Narnia?

CNN is reporting that based upon a previously unpublished letter that Lewis would have been against the upcoming Narnia film. After reading the letter it is clear that in 1959 animation had not reached the quality it has in 2005, so Lewis was opposed to it then. I tend to think that Lewis would have approved of the upcoming version. I think his real concern, based on the letter, was that the sense of fantasy and seriousness of the books would be lost by silly looking animals made to lip-sync voice overs - hence why he preferred a cartoon to live action. Lewis above all took the fantasy seriously and thought that it had to be taken seriously to have the intended effect - and the quality of current CGI technology allows that to happen. In the end this CNN report is an anachronistic attempt to sabotage what, by all accounts, is going to be a great film.
