I’ve seen people talk about actors and artists that had a terrible time.
My own would be Anne Rice. She wrote Interview with the Vampire after her young daughter died of Leukemia. Then her husband suddenly died of a brain hemorrhage. I suspect her Christian, anti-fanfic phase was a result of mental illness and manipulation from the publishers, although I don’t think she ever apologized.
And the reason it became popular is because it was so unknown, it was cheap to publish so the US government sent thousands of copies to soldiers during WW2 who then came home and felt it was a “classic”. It wasn’t well-received in Fitzgerald’s time at all.
