Do you know what a cargo cult is?

It is very strange but I did hear about it the first time I was in Australia, but it was related to PNG, Papua New Guenia. Read here:

I have seen a movie in Japan when a group of people think atom bomb is God. However I do not remember the name or the producer.
I recently received an email regarding cargo cult film premiere notice:

Cargo cult is best described from the waitingforjohndoc.com site as shown in the next image:
