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.
david cornwell, aka john le carre - his father was an absolute piece of shit, a liar, conman, abuser. when i found out the meaning of the title of his autobiography, the pigeon tunnel, i was horrified.
