The Da Vinci Code, set to open in theatres next week, is a betrayal of Islam and should be boycotted, a Calgary Muslim leader says. Sayed Soharwardy, president of the Islamic Supreme Council of Canada, said the film and bestselling novel it's based on mocks his religion by questioning one of Islam's most important prophets: Jesus Christ. "Dan Brown used the real Jesus to propagate his fabricated re-search," he said."This kind of movie is not frequent but if we don't stand up to these movies, they'll become more frequent."The movie, which opens May 19, suggests Jesus had a child with Mary Magdalene and the ancient bloodline still exists, a secret fiercely protected by a sect of the Catholic church. Soharwardy said because the film taints the notion of Jesus -- the most oft-mentioned prophet in the Qur'an -- as pure and sinless, it could convince people the story is real.
