National Geographic Channel - Unlocking Da Vinci's Code

Was Mary Magdalene the wife of Jesus Christ—perhaps even the mother of his child? Are descendants of this holy family still alive today? It has been reported that a secret society, said to have included Leonardo da Vinci and Sir Isaac Newton, knew and kept this extraordinary secret for centuries. But did da Vinci embed hints to the truth in his paintings?

Follow Elizabeth Vargas as she investigates claims
from Jerusalem to England in a quest to separate fact from fiction.

yes, in fact I just finished watching it. Like I said in my other post, if you are familiar with the theories surrounding Da Vinci's code, and the Knights Templar...then this video will not add anything to what you already know.

It's still interesting to watch. Focuses mainly on Mary Magdalene. Just so you know.
