The movie "The Island"

We saw the movie The Island yesterday. It is really chilling to see how people can be deceived into believing almost anything.
It's up on par with other cult movies:

The Beach
The Village
The Island

If you need to explain what it's like living in a cult these movies can give an "outsider" somewhat of an idea... the way the leaders give you fear of the "outside" and how you are "special".
