Khufu Revealed (2008)

Superb documentary on the continuing mystery surrounding the construction of the most 'enigmatic' of all the pharaonic constructions, the Great Pyramid of Giza (Khufu).
The documentary follows the French architect Jean-Pierre Houdin as he puts forward his fascinatingly plausible theory on pyramid construction, namely that the Great Pyramid could have been built ...from the inside!
