Benson Y. Parkinson of the Association for Mormon Letters noted that Christof represented Jesus as an "off-Christ" ("Christ-off") or Antichrist, comparing the megalomaniacal Hollywood producer to Lucifer. The conversation between Truman and Marlon at the bridge can be compared to one between Moses and God in the Book of Exodus.
In C.S. Lewis and Narnia for Dummies by Rich Wagner, Christof is compared with Screwtape, the eponymous character of The Screwtape Letters by C. S. Lewis.
"This was a dangerous film to make because it couldn't happen. How ironic."Director Peter Weir on The Truman Show predicting the rise of reality television
In 2008, Popular Mechanics named The Truman Show as one of the 10 most prophetic science fiction films. Journalist Erik Sofge argued that the story reflects the falseness of reality television. "Truman simply lives, and the show's popularity is its straightforward voyeurism. And, like Big Brother, Survivor, and every other reality show on the air, none of his environment is actually real." He deemed it an eerie coincidence that Big Brother made its debut a year after the film's release, and he also compared the film to the 2003 program The Joe Schmo Show: "Unlike Truman, Matt Gould could see the cameras, but all of the other contestants were paid actors, playing the part of various reality-show stereotypes. While Matt eventually got all of the prizes in the rigged contest, the show's central running joke was in the same existential ballpark as The Truman Show." Weir declared, "There has always been this question: Is the audience getting dumber? Or are we filmmakers patronizing them? Is this what they want? Or is this what we're giving them? But the public went to my film in large numbers. And that has to be encouraging."
Ronald Bishop's paper in the Journal of Communication Enquiry suggests The Truman Show showcased the power of the media. Truman's life inspires audiences around the world, meaning their lives are controlled by his. Bishop commented, "In the end, the power of the media is affirmed rather than challenged. In the spirit of Antonio Gramsci's concept of hegemony, these films and television programs co-opt our enchantment (and disenchantment) with the media and sell it back to us."
Simone Knox, in her essay "Reading The Truman Show inside out" argues that the film itself tries to blur the objective perspective and the show-within-the-film. Knox also draws a floor plan of the camera angles of the first scene.
Psychological and psychoanalytic interpretation
An essay published in the International Journal of Psychoanalysis analyzed Truman as
[A] prototypical adolescent at the beginning of the movie. He feels trapped into a familial and social world to which he tries to conform while being unable to entirely identify with it, believing that he has no other choice (other than through the fantasy of fleeing to a far-way island). Eventually, Truman gains sufficient awareness of his condition to "leave home"—developing a more mature and authentic identity as a man, leaving his child-self behind and becoming a True-man.
Parallels can be drawn from Thomas More's 1516 book Utopia, in which More describes an island with only one entrance and only one exit. Only those who belonged to this island knew how to navigate their way through the treacherous openings safely and unharmed. This situation is similar to The Truman Show because there are limited entryways into the world that Truman knows. Truman does not belong to this utopia into which he has been implanted, and childhood trauma rendered him frightened of the prospect of ever leaving this small community. Utopian models of the past tended to be full of like-minded individuals who shared much in common, comparable to More's Utopia and real-life groups such as the Shakers and the Oneida Community. It is clear that the people in Truman's world are like-minded in their common effort to keep him oblivious to reality. The suburban "picket fence" appearance of the show's set is reminiscent of the "American Dream" of the 1950s. The "American Dream" concept in Truman's world serves as an attempt to keep him happy and ignorant.
