Friday the 13th: The Crystal Lake Massacres Revisited is a 2009 mockumentary serialized as a bonus feature on the Deluxe Editions of Friday the 13th: The Final Chapter, Friday the 13th: A New Beginning, and Friday the 13th Part VI: Jason Lives. It features interviews with Crystal Lake locals, historians, and family members of murder victims, and introduces the idea that many consider the Crystal Lake murders to be the work of copycat killers like Roy Burns rather than a single particularly persistent murderer.
