If Hollywood is to be believed, we need nuclear missiles, computer viruses, tin foil hats and a reasonable amount of  quiet pleading to rid the world of invading alien life forms.

But then, I’m figuring not too many people would go to see a movie in which an apocalyptic invasion was averted by a gang of merry punters wearing deely boppers and facepaint while having a good old dance in a field.

Seems just as effective though, no?
