I have seen a lot of threads discussing relationships with "The Truman Show" but I'd like to throw out a very obscure 1980's movie called "Control" aka "Giorno Prima, Il". I was just 11 years old when this came out but I watched it a ton. Anyway...basically a bunch of volunteers are put in a fallout bunker to see how they could survive cramp conditions.. I'll put the rest of the plot in spoiler font in case someone can find this movie and wants to watch it..

During their stay a "war" breaks out and they have many conflicts with everything from who's in charge to who has weapons to using the weapons...in the end it was just a test to see how they would react if there really was a war

This movie has many similarities to LOST.
