Olivia Colman and Josh O'Connor previously starred as Queen Elizabeth II and her son, Prince Charles, in the acclaimed series The Crown (2016).
Before signing on to direct, Eva Husson had found the book profoundly moving, she said. "I first read it at the novel stage, and I remember I read it very, very quickly in one sitting. I closed it and I literally burst into tears for 20 minutes without any specific reason, but it just cracked something open and made me feel some sort of frequency."
The book which Donald gives to Jane on their first dinner together is Virginia Woolf's "A Room of One's Own".
