I want to know the answer to the following question:
When does 'The Kidnapping of Edgardo Mortara' take place?
All the background I'm provided with is that "After completing filming on Ready Player One, while it is in its lengthy, effects-heavy post-production, he will film his long-planned adaptation of David Kertzer's acclaimed The Kidnapping of Edgardo Mortara.". Is that enough to answer the question?
