The Gorilla

I've seen this so many times on here: long-winded dissertations about movies that are supposedly lost (witness "London After Midnight!"). How can someone truly discuss something that doesn't even EXIST anymore? (Isn't that something akin to various religious groups prohibiting some movie because it's blasphemous, despite the fact that no one in that group has ever seen the movie?)

Three possible apologies are in order before the fact, though: 1. The previous commentator (the one who set me off on this) is old enough to HAVE seen the movie. 2. All the rest of us are wrong, and the movie IS extant (PLEASE tell us where to find it!!!) 3. Just an apology of my own, for having used this forum for a brief editorial.
