Ms Wray was the damsel in distress, Ann Darrow, in the 1933 film King Kong. The budget did not stretch to pearls for her scenes in this movie. Happily, in the 1976 remake with Jessica Lange as Ann Darrow, pearls were supplied, hundreds of them! She had the neck to carry it off.
Director Peter Jackson remade King Kong in 2005 with Naomi Watts as Ann Darrow. She wasn't adorned with pearls in that movie, but she likes to wear them, her short hair and amazing clavicles showing them off beautifully.
