"The Da Vinci Code," directed by Ron Howard and based on Dan Brown's novel, is a work of fiction that incorporates real historical figures, art, and locations. While it draws on actual elements, such as Leonardo da Vinci's works and the Priory of Sion, the plot itself, including the conspiracy theories surrounding the Holy Grail and Mary Magdalene, is fictional. The film combines historical facts with imaginative storytelling, making it a blend of reality and fiction rather than a true story.

"The Da Vinci Code," based on Dan Brown's novel, follows symbologist Robert Langdon as he investigates a murder in the Louvre Museum. The main point revolves around the quest for the Holy Grail and the secrets of Christianity, suggesting that Mary Magdalene was married to Jesus and that their bloodline continues today. The film explores themes of faith, history, and the conflict between religion and knowledge, as Langdon and cryptologist Sophie Neveu uncover hidden truths that challenge established beliefs.

"The Da Vinci Code" is banned in some countries due to its controversial portrayal of Christianity and its speculative interpretations of historical and religious figures, particularly regarding the role of Mary Magdalene and the concept of the Holy Grail. Critics argue that it undermines traditional Christian beliefs and promotes conspiracy theories about the Church. Countries such as Egypt and Lebanon have restricted its screening to protect religious sentiments, reflecting concerns over blasphemy and potential societal unrest.

There are three movies in the "Da Vinci Code" film series, based on the novels by Dan Brown. The first is "The Da Vinci Code" (2006), directed by Ron Howard. It is followed by "Angels & Demons" (2009), also directed by Howard, which is based on another of Brown's novels. The third installment is "Inferno" (2016), again directed by Howard, based on Brown's book of the same name. These films feature Tom Hanks as the protagonist, Robert Langdon.
