In the 2006 film The Da Vinci Code, Tom Hanks plays symbologist Robert Langdon during the Holy Grail investigation.
The film adapts Dan Brown’s 2003 novel and follows Langdon after the murder of Jacques Saunière at the Louvre. Langdon works with Sophie Neveu to interpret clues involving Leonardo da Vinci, Christian history, secret societies, and the Grail.
The story uses the Grail in a highly revisionist way. Rather than treating it only as a physical cup, it connects the term with a hidden bloodline and with Mary Magdalene. These ideas belong to the novel and film’s fictional conspiracy narrative, not to established historical evidence.
Tom Hanks returned as Robert Langdon in Inferno, released in 2016. The character’s role as a Harvard professor of symbology is central to both screen adaptations.
