Blade Runner does not seem to be farfetched or fantasy-like due to it's basis in the
science and technology of the present and the presentation of familiar objects in the
sets. For example, the existence of the replicants themselves would seem far-fetched and
absurd in less developed movies, but Ridley Scott convinces the audiece of the possibility
of such beings through the discusssion of their creation. Scott shows the man who makes
the eyes of the replicants, he shows a discussion of their basic brain function, and
shows Tyrell discussing the basis for memory implants, all of which gives the viewer reasons
to believe that replicants could exist.
Also Ridley Scott's set contains many billboards and other memorabilia that exist in the
present. For example, by showing a large Coca-Cola billboard in several outdoor scenes, Scott
gives the viewer something to grasp in the present. It allows a person watching the movie
to believe that the movie is a portrayal of the future and that we are heading towards
a reality of replicants and other worlds.
Ridley Scott, in the creation of Dr. Tyrell, defines a character symbolically representing
a detached god. Tyrell creates replicants that are set free on society only to be restrained
through their inevitable death. This is similar to many people's view of God, as a creator
who just watches his creations in society, only to pull the strings on their death at some
point in the future. This parallel of Tyrell as God could be taken even further to include
Roy's meeting as judgement day. Roy meets his maker and questions his existence and the possibility
of prolonged life, just as man would like to question his God on the fundamental questions
of life. Also Tyrell judges Roy's life as full and enterprising which is definitely likened
to the Christain viewpoint of judgement at the end of one's life.
Furthermore, if Tyrell is the
creator then Deckard is the Grim Reaper, or death itself. In many religious beliefs there
is a divinity likened to death that terminates peoples lives for the Creator. Obviously
Deckard would satisfy this requirement, for he is killing for Tyrell.
The strong symbolic reference of Tyrell as God heightens the strory by taking
it to another level, and enhancing the plot through stonger characterizations and
development.
