After Paramount bought the Smithsonian Channel (where the original production was released), they cut this documentary by more than half, editing it down to 45 minutes. Only the cut-in-half version now airs on the Smithsonian Channel's streaming service. This cut version of course also streams on Paramount+ and Amazon Prime Video's Paramount+ Channel. The original 92 minute version was issued on DVD and is still available on Amazon Prime Video itself for streaming.
