The Penis is Evil

From the sci-fi 'classic' Zardos:

Zardoz: The gun is good. The penis is evil. The penis shoots seeds, and makes new life to poison the earth with a plague of men, as once it was. But the gun shoots death, and purifies the earth of the filth of brutals. Go forth... and kill!

Yes, that's Sean Connery, and he wears it for the whole movie.

In 2004 the magazine Total Film described Connery's costume (consisting of a ponytail wig, leather knee boots, and a loincloth which bears a strong resemblance to a giant orange nappy or diaper) as the number 1 "dumbest decision in movie history".
