I would guess this video was done sometime in the 1990s. Matthew Hall discusses his personal connection to DS and his experience working on the 1990/91 series. This is one of the few occurrences of which I am aware in which someone close to the show has actually described Dan Curtis as "the head writer" of the series. I still think DS (the original series) was so good *in spite of* Dan's input... people who are really close to a project often take a different view from those who are spectators--or have a more objective vantage point:
