I just heard from a reader who saw my documentary “Gargoyles: Guardians of the Gate.” Long time readers — or to be more accurate, long time readers of my column — may recall that I used to be a television producer. In 1994, I wrote and produced a documentary on Gargoyles on a budget that makes “shoe string” sound lavish (5 cities: Paris, Oxford, New York, Princeton, Washington DC for about 20 grand). It was something of a hit — in a very narrow sense — and has been bobbing around the world of public television for years. Still, I assumed it was long gone by now. But lo’ and behold it’s still being played. I wonder if the gnomes in the PBS world know it was written by a trogladytic National Review conservative.
