I conjecture that Christof (God, for obvious reasons) constructs a perfect world for Truman (who I conjecture follows what I’ll call the Lucifer analog). Looking at the actions of Christof, you can interpret all of them as benevolent. When Christof does "negative" things to Truman the motivation is to protect Truman from pulling back the curtain and seeing the illusion. He seeks to protect Truman from revealing that Seahaven (heaven) is not entirely a true world. He sacrifices things for Truman for the greater good of living in what he sees as a perfect world. He sits in the moon (the Truman version of an Ed Harris mission control) and runs the show. He commands everything from weather to stoplights. In Truman’s world, he is the power above and the unseen, almighty ruler. During the final scenes, Christof looking at a monitor with Truman on it, which he then strokes, as if he’s trying to comfort him. As he tries to persuade Truman, the later remains facing towards the door, showing that he’s defying his god. After a series of shots of viewers watching the event, Truman says his catchphrase, bows, and exits the show, disappearing into the blackness of the hallway.
Throughout the beginning of the film, Truman is surrounded by perfection, and he does live a pretty great life. Christof sees to it that the world around him is pretty god damn fantastic, to the best of his ability, but Truman elects to leave Seahaven because he ultimately has no CONTROL over the world around him. He does not like being subject to omnipotence and the material aspects of the alternative; they are not important compared to having control of his world. Some might say that Truman is Lucifer, seeing that Truman rebelled against Christof, climbing Jacob’s Ladder to a world where he becomes his own god. That world is called Earth, a juxtaposition to the Christian Doctrine. The ladder represents a progressive advancement from a lower to a higher sphere "...This is none other than the house of God, and this is the gate of heaven" In most cases the ladder or stairs lead to an illuminated light, fixed upon the eye of providence, this can be seen in freemasonry but the film shows the gate of darkness and blackness, illustrating the planet we call earth. In the thumbnail and video you’ll notice that Truman sits a top the stairs leading into darkness. His arms and body spread out like a cross. What does it say about philosophy and religion when Truman finally meets his Creator and decides to go his own way, out of the cradle of light and through the literal dark passageway into the great unknown?
Truman can not be Lucifer considering, Lucifer knew full well, where he was and who God was. He was not being deceived. Lucifer was God's most favored angel and basically second-in-command of heaven. By contrast a huge amount of effort is expended to keep Truman ignorant of the truth of his existence. Truman is escaping from a sort of resort-prison where he is actively being deceived by everyone around him. Lucifer, by contrast knows exactly what, and who, he is rebelling against. It's more like he is quitting a dream-job. So, in brief he wanted to usurp God and rule Heaven and Earth. Truman's motivation is finding the truth. I suppose the largest difference is the knowledge of each other. Truman is unaware of his situation, therefore he cannot be said to disapprove of it, like Satan did. Perhaps you can use Truman as an allegory like "Everyman", where he can represent any and every individual at once and the plight is not Satan's downfall, but Man's journey to discover his own destiny through free will. Furthermore, Lucifer/Satan is still under the control of God (much like the Jins), but have the role of tempting humans: Lucifer/Satan gets to fulfill his desire of exposing humanity as the imperfect and unworthy beings that we are.
Side note: (The film could also be a religious metaphor, but the Creator/Christof isn't god [the play on words Christ(off) gives us some direction], he's the Deceptive Demon from the philosophical works of René Descartes, who has created an artificial world, so rather than Heaven, Seahaven is a form of hell. The sea representing the depths or abyss. In so, that when Truman climbs Jacob’s ladder he is merely climbing up from a sort of hell to the sphere known as earth. Also, when I first saw the film I was reading a lot about Gnosticism, and I think it matches the Demiurge myths rather closely.)
Anyway, the reason this is cool perspective is in Christian literature the audience will by default side with God/Christof, in his infinite benevolence, but in The Truman Show everything is done to endear Lucifer. The choice of Lucifer is always about the desire to have dominion over your own destiny, and an acknowledgement that the material artifacts of your world are second to that level of control. So, Christof is sovereignly controlling Truman’s world – even the Sun and the storm at sea (both have biblical equivalents), and we also see him masterfully orchestrate the world as perceived by the viewing public.
Now for the details.
The biblical Fall of Man, where Adam (Truman) and Eve (Sylvia playing Lauren Garlan), living in the Garden of Eve (Show) in total obedience to God (Christof) and his partner named Moses., tempted by the serpent (Free Will) to eat from the Tree of Knowledge (Freedom), becoming ashamed of their nakedness (realizing how everyone is an actor), and expelled (Escapes) from the Garden (Show).
Sylvia, I believe is Eve who was hired to play a background extra, a fellow student at Truman's college, named Lauren. She became romantically involved with Truman and tried to reveal to him the truth, but was thrown out of the show for doing so. She then becomes a protester against The Truman Show, urging Christof (God) to release its lead (Truman). Sylvia hinted to Truman that his world might not be what he thinks it is. She tempts him to see through the illusion but seeing that Truman (born into this world) can not fully comprehend the illusion in its entirety, it will take him many more years to piece together this supposed truth. Through those years, he will obtain pieces of fragmented knowledge of which will lead him to what is portrayed as Gnosis. It should also be noted that Eve was tempted first by the fruit and found free will while still in Eden, and then imparted it to Adam (Truman), a close parallel to Lauren/Sylvia. So, I think the love interest in this film might be Lucifer in this story. Sylvia is one of Christof's (God) rogue actors which can be seen as an Angel who works for God but eventually defies Him by giving the gift of knowledge to our Adam character. She is cast off of the set and fired (sent to hell, earth), where Adam (Truman) will meet her again.
It should also be said that during the scene where Sylvia tries to reveal the illusion to Truman in the library (knowledge) , her entire face looks to be morphed; she smiles cunningly as if she is being tempted by the serpent. Watch the movie and you'll understand what I'm saying.
The very first example of Truman attaining a hint of “gnosis,” or knowledge, that he’s living in a fake world is from a studio light that falls out of nowhere from the sky. As Truman picks up the mysterious light, the words “Sirius 9th Canis” are written on its label.
Sirius, the ninth closest star to earth, is the brightest star in the Canis Major star constellation, also known as “Big Dog.” What is markedly interesting, is the scene just before the falling of the “Sirius 9th Canis” studio light. We see a large dog jump on Truman as he heads to work. The dog appears to be bigger than Truman and stands up on his hind legs. The relationship between a dog (apart from the name) and this constellation is well known in astrology because it looks like a LARGE DOG STANDING ON ITS HIND LEGS, hence the name “Big Dog.”
Sirius is also known colloquially as the "Dog Star", reflecting its prominence in its constellation, Canis Major (Greater Dog). The heliacal rising of Sirius marked the flooding of the Nile in Ancient Egypt and the "dog days" of summer for the ancient Greeks.
Dog Days , the phrase invokes the hottest, most stifling days of summer. The 40 days, beginning July 3 and ending August 11 coincide with the heliacal (at sunrise) rising of the Dog Star, Sirius. Now go back a scene before the dog jumped on Truman. In the morning, Truman and his neighbor talk about the weather and how hot it is.
Furthermore, Sirius is visible together with the constellation of Orion, the Egyptians worshiped Orion as the god Sah. The soul of Isis is called Dog by the Greeks", meaning Sirius worshiped as Isis-Sopdet by Egyptians was named the Dog by the Greeks and Romans. The 70-day period of the absence of Sirius from the sky was understood as the passing of Sopdet-Isis and Sah-Osiris through the Egyptian underworld.
The star Sirius has long been worshiped in the occult world as Lucifer (The morning star). So in short, Truman, or true man, got his knowledge that he was in a controlled paradise from the brightest star.
“How you have fallen from heaven, O morning star, son of the dawn! You have been cast down to the earth” (NIV).
The movie ends with Truman breaking free from the world Christof has created for him by stepping through a door into darkness. The onlooking world cheers as Truman becomes the god of his own future.
