[2] Charlton Heston is the host of the documentary, which features John Anthony West and geologist Robert M. Schoch.

The documentary was first aired by NBC as an hour long prime time special on 10 November 1993.

[4][5] Mystery was initially released by Goldhil Home Media as a 95-minute "extended version" on VHS in 1994,[6] and re-released on DVD by UFOTV as a 95-minute "Special Edition" in 2005.

It still contains the core material and is worth watching, but when you do so, please disregard the nonsense 'filler' that was inserted into an otherwise great show.

"[8] John Anthony West received a News & Documentary Emmy Award in the "Outstanding Individual Achievement in a Craft: Researchers" category for the program on 8 September 1994.
