10 Bad Nuns: Sister Ruth and Sister Aloysius Beauvier

In joint 10th position comes two of the"rotten apples" in the barrel.
Sister Ruth (Kathleen Byron) is one of the most memorable sex crazed would-be-killer nuns in cinema history.
With her red vampire eyes and slash of scarlet lipstick, I was frightened silly (as a ten year old child) when she tried to fling the virtuous Sister Clodagh (Deborah Kerr) from the Himalayan Bell Tower in Black Narcissus
Sister Aloysius Beauvier (The pig eyed Meryl Streep) was one of those old fashioned and bitterly strict school nuns that existed ( and probably still do) in every catholic school .
