Secrets of the Serpent: In Search of the Sacred Past (2006)

Based on Philip Gardiner's theory that an ancient serpent cult once dominated the human race, this program explores mysterious locations sacred to the cult, undisclosed information about the Holy Grail and the Elixir of Life, and the massive conflict that led to the sect's demise as Christianity took over. Controversial researcher and best-selling author Gardiner's intriguing documentary complements his novel of the same name.

Unfortunately the movie Secrets of the Serpent: In Search of the Sacred Past is not yet available on HBO Max.
