Double dip for 'Crystal Skulls'

Documentary to hit shelves in same day as 'Indiana Jones'

Piggybacking is alive and well.

To capitalize on Paramount's Oct. 14 DVD and Blu-ray Disc release of "Indiana Jones and the Kingdom of the Crystal Skull," independent supplier Infinity Entertainment Group is releasing that day "The Legend of the Crystal Skulls."

The documentary details the Smithsonian Institute's quest to determine through science the truth behind the real-life "crystal skulls" that have been discovered since 1926.
