Eldon Tyrell from Blade Runner was supposed to be replicant

The character of Dr. Eldon Tyrell is presented as a kind of deity figure who has the power of creating life, but unable to prevent death. In the original screenplay Ridley Scott wanted this character as well as Deckard to be a replicant. During the development of the original story-line the Tyrell Corporation megastructure building is actually a pyramid, and at the base of this is a cryogenic chamber which houses the body of the real Tyrell. The replicant Tyrell, by creating near human genetically engineered machines is also trying to discover a way to bring the real Tyrell back to life. Another variation had the bones buried beneath the building protected by the mysteries of 'pyramid power'.
