If you were writing a report, it would probably be a market analysis. You could call it: Why a Sequel to The Truman Show Would be Profitable.
In order to convince an executive that he or she should fund your show, you will need to show that the first production was successful. There are many reasons for this success. It ran for many years through Truman’s entire childhood and early adulthood. It made a great deal of money on product placement. The star, Truman, did not draw a salary because he did not even know he was being filmed.
The question is which of these conditions you could replicate. Chances are you could still have a long-running show and could still use product placement. You would need to have consent from the cast members though. Many people would want to be on television so badly that they would probably work for very little.
Christof says in the movie that one of the greatest factors of success for the show is that it is real.
We've become bored with watching actors give us phony emotions. We are tired of pyrotechnics and special effects. While the world he inhabits is, in some respects, counterfeit, there's nothing fake about Truman himself. No scripts, no cue cards. It isn't always Shakespeare, but it's genuine. It's a life.

This would be a big part of his sales pitch. Even with people who knew they were being filmed, you could recreate some of the genuineness. The truth is Truman was the only one not being scripted. Christof fed lines to everyone else. You could create a reality show where no one is given a script, and it would be just as successful even if they knew what was happening.
