Brace yourself. James Cameron, the man who brought you 'The Titanic' is back with another blockbuster. This time, the ship he's sinking is Christianity. In a new documentary, Producer Cameron and his director, Simcha Jacobovici, make the starting claim that Jesus wasn't resurrected --the cornerstone of Christian faith-- and that his burial cave was discovered near Jerusalem. And, get this, Jesus sired a son with Mary Magdelene. No, it's not a re-make of "The Da Vinci Codes'. It's supposed to be true.
