SPOILER ALERT! DON’T READ ON IF YOU HAVEN’T READ (OR SEEN) ‘ROSEMARY’S BABY’!
Comparison:
Both scripts follow a woman whose pregnancy is controlled/manipulated by a supernatural force while the people around her either don’t believe her or seem to be complicit. However, ROSEMARY’S BABY ends in defeat, with Rosemary accepting her monstrous child, whereas DUE ends in hard won triumph, with Nina using the entity’s own deal mechanics against him.
The key distinction is agency: Rosemary is a victim to the end, while Nina moves from victim to protector.
Both great scripts by the way
