Query: A timeless science fiction movie. An instant classic.

I am a lover of good science fiction. But often times, sci-fi tends to cross the line without any good reasoning. This movie explores the improbability of an un-aging man but does so by building credibility despite obvious skepticism. A nice climax too.You could watch a movie like this 100 years from now and it would still be good. And it could have very easily be made/written a 100 years ago. Such an interesting concept. I hope that an extended version of this to be made into a TV series. There is so much more to it.I can understand some religious fanatics poorly rating this movie, but that's what you would expect if from them.I am going to read more from this author. I can't believe this movie was not as popular in the theaters. If anyone reading this comment has suggestions for good sci-fi please let me know.
