The Da Vinci Detective

The Da Vinci Detective was a feature length documentary for Channel 4, commissioned as the channel’s response to the Da Vinci Code phenomenon.

At its heart it was a scientific thriller, telling the story of forensic scientist and art historian Maurizio Seracini as he explored two mysteries surrounding masterpieces created by Leonardo Da Vinci -
The Adoration of the Magi and the lost Battle of Anghiari. One reviewer called it a blockbuster, and it was designed to be big. The locations were on occasion epic and the art on display was uniformly stunning.
