I couldn't make out the title while watching the movie, but the cover had a cat on it. The screenplay doesn't mention it either. The movie probably won't be available on streaming for several months, so I was wondering if anyone here knows what it was.
This is the information you gave us and the picture:
- the cat on the cover
- the title than we can barely read
But the words seem to fit the title of a book that often has a cat on its cover. And the closest thing I can come to with this data is The Master and Margarita from Soviet writer Mikhail Bulgakov (1st published in English 1967). The manuscript was not published as a book until 1967, in Paris.
If she's reading in French, then the title would be: "Le Maître et la Marguerite" and it still would fit what we see on the image.
