Host Richard Crenna reviews various theories on the existence of a site for the legendary Atlantis described by Plato and envisioned by mystic Edgar Cayce.

Atlantis: In Search of a Lost Continent

GREECE: SECRETS OF THE PAST, directed by two-time Academy Award®-nominated filmmaker Greg MacGillivray, is the stirring story of how a Greek archeologist of the 21st century is uncovering the secret history of his ancient ancestors who forged a society that continues to astound the world today with its ideas, inventions and achievements. Set against the breathtaking, azure vistas of the Greek Isles, the film merges a contemporary archeological “detective story” with some of the most advanced and painstaking digital re-creations ever undertaken for an IMAX® theatre film, with scenes that restore such centuries-old spectacles as the original Parthenon and the volcanic eruption that buried Santorini in 1646 BC.
