Dan Brown’s novel The Da Vinci Code sparked a cultural phenomenon which has led millions of people to explore the mysteries of the isolated hilltop village of Rennes-le-Château. Behind the fiction of the novel is a wealth of detail originally uncovered by Henry Lincoln in his book Holy Blood, y Grail. Michael Botts documentary Origins of the Da Vinci Code features writer Henry Lincoln leading the viewer through a variety of facts uncovered by him during his study of the Da Vinci Code and its history. He did much of this work in the years before Dan Brown popularized the topic with his successful novel. The documentary touches upon topics like the history of the Rennes-le-Chateau, how Lincoln discovered the codes, and the Invisible Temple.
