Are you familiar with Bloodline of the Holy Grail: The Hidden Lineage of Jesus Revealed, by Laurence Gardner?
(http://www.amazon.com/exec/obidos/ASIN/1931412928/qid=1113009261/sr=2-2/ref=pd_bbs_b_2_2/102-5300178-9102536)
Gardner lays out an interesting argument that Moses and Akhenaten (born Amenhotep IV) were the same person. I wonder if this movie will be drawing on this source.
No, I haven't. I suspect that they may be influenced by the enormous success that jerk Brown has had with The Da Vinci Code.
