In 2005, UK TV personality Tony Robinson edited and narrated a
detailed rebuttal of the main arguments of Dan Brown and those
of Baigent, Leigh and Lincoln, "The Real Da Vinci Code", shown on British TV Channel 4. The
program featured lengthy interviews with many of the main protagonists cited by Brown as "absolute fact" in
The Da Vinci Code. Arnaud de Sede, son of Gérard de Sede, stated categorically that his father and Plantard had made up the existence of the Prieuré de Sion, the cornerstone of the Jesus bloodline theory - to quote Arnaud de Sede in the program, "frankly, it was piffle". The program also cast severe doubt on the Roslyn association with the Grail and on other related stories like the alleged landing of Mary Magdalene in France.
Detailed analysis of many other claims by Brown in
The Da Vinci Code in the program showed them to be unverifiable or unhistorical.
