There is a theory, first publicized in The Templar Revelation by Lynn Picknett and Clive Prince, that the person to the left of Jesus (to his right) is actually Mary Magdalene, rather than the apostle John (as all art historians identify it). This theory is central to Dan Brown's popular novel
The Da Vinci Code. In the book, it is said that John/Mary Magdalene has a womanly bosom, feminine facial features, and is swaying gracefully toward Peter. Peter appears to be making a threatening gesture across Mary's throat. The author uses this theory to advance his view that Leonardo da Vinci was once the head of a secret society, the Priory of Sion, which protects the secret of Jesus' royal bloodline, and where his descendants live today.

Seems the critics didn't care for the movie much either.
"The Cannes audience clearly grew restless as the movie dragged on to two and a half hours and spun a long sequence of anticlimactic revelations."
"I kept thinking of the Energizer Bunny, because it kept going and going and going, and not in a good way," said James Rocchi, a film critic for CBS 5 television in San Francisco and the online outlet Cinematical. "Ron Howard makes handsome films. He doesn't make bad ones, but he doesn't make great ones."
"One especially melodramatic line uttered by Hanks drew prolonged laughter and some catcalls, and the audience continued to titter for much of the film's remainder."
"Some people walked out during the movie's closing minutes, though there were fewer departures than many Cannes movies provoke among harsh critics. When the credits rolled, there were a few whistles and hisses, and there was none of the scattered applause even bad movies sometimes receive at Cannes"
