based on a novel?
Is this really based on a novel by Naguib Mahfouz? Does anyone know the title of the novel? I see on wikipedia that Mahfouz also wrote screenplays, and because no title for the novel is given here, and he hasn't written a book with the same title as this movie, I wonder if it really is based on a novel or if he wrote it as a screenplay.
If anyone can answer this question for me, I will be grateful! Thank you in advance!
