[The Truman Show] why didn;t they have several unknowing actors in Seahaven?

multiple people were put up for adoption, and it seems like they'd be running a lower risk of escape, while allowing several programs to run simultaneously for about the same mount of money.

A couple of reasons:

1. The Truman Show didn't start out in Seahaven. Obviously in the modern era we think of it as being set there, but in the early years it was entirely within one house, with video camera technology that by modern standards is quite crude. It was only after The Truman Show had been running for a few years and proven a hit that the Seahaven "set" was built.

2. Running several programs simultaneously would dilute the brand and reflect poorly on the property. The Truman Show is funded through advertisement, and it's on 24 hours a day. Making a spin-off of some kind would split the viewers and make advertising dollars slow down.

3. Having the whole town be exclusive to Truman allows for a lot of localized effects that simply wouldn't be possible to do with multiple people at once. With just Truman, the sun can be positioned to frame him just right, it can rain for dramatic effect, etc. But with two or more people in play, this would get cumbersome. Furthermore, it would be difficult to control simultaneous story beats.
