The Rennes-le-Chateau Research and Resource website have made available online the entire Shadow of the Templars documentary, from which grew the seminal hidden history books Holy Blood, Holy Grail and The Messianic Legacy (and, despite the legal view, The Da Vinci Code):
In 1974, British script writer Henry Lincoln introduced the Mystery of Rennes-le-Château to the English speaking world through his documentary “The Priest, the Painter and the Devil”. The documentary created a storm of publicity and eventually led to the production of a 2nd documentary in 1979, Shadow of the Templars, which you can see on this page. This documentary was already co-researched by Michael Baigent, which later led to Henry, Michael and the late Richard Leigh writing the international bestseller Holy Blood Holy Grail.
The script and presentation of Shadow of the Templars were done by Henry Lincoln. It was produced by Roy Davies for the BBC Chronicle series.
Shadow of the Templars marks the beginning of the mythos of the Priory of Sion entering the public consciousness (at least in the English speaking world), and features all the main ‘characters’, from the village of Rennes-le-Chateau to that man of mystery, Pierre Plantard. Fun to watch!
The online video is broken into four parts, for ease of viewing.
