The reality of the television show is that this is precisely what is happening as Truman unwittingly offers his entire life, twenty four hours a day, for his television audience to feed on. While not every camera used in the film is diegetic, when they are, they are used deliberately and expertly.
He is the villain in the film. Non-diagetic and diagetic sounds are used in almost every scene in the Truman show.
This makes the audience wonder what does happen at the end. Also, Truman starts to notice other things, he predicts a lady with flowers, then a beetle, and then a couple would come around the corner.
He just wants to be free from being watched and controlled his entire life, and the hidden cameras symbolize that force throughout the film. The whole show symbolises real life.
This was very significant to me because it shows Truman conquering all the people that had lied to him and beating them at their own game. From that moment on, Truman starts to get suspicious.
We identify with Truman and psychologically become a part of his world. Titles are shipped on receipt of payment. This image is itself framed by the outlines of the cabinet door.
This helped set the scene a little more. Peter Weir gives off many messages during the Truman Show, He is laughing at the media all the way through and portrays them as a very powerful, untrustworthy organisation.
