I have an RSS feed that monitors information on the Pope; this morning it rewarded me with this neat British documentary on YouTube in which then Cardinal Joseph Ratzinger takes the filmmakers on a tour of the Vatican (the film was shot when he was still a Cardinal, though before it was released, he became Pope, so the film references that fact). It's pretty interesting. Unfortunately, it's only the first ten minutes of the 45 minute documentary. The entire thing is available on DVD at their site.
It is a little amusing because the filmmakers come at the subject with very little knowledge of the Church -- or are presenting it to viewers whom they assume have very little knowledge of the Church -- so it is a little gossipy and conspiratioral in its tone. Still, some good photography and some neat behnd-the-scenes stuff.
