As per the Netflix Tudum report dated August 26, Stone said,
“You never question whether or not she saw what she saw…You agree completely with her. It’s her struggle against the conspiracy.”

The Woman in Cabin 10 release, credits and what changed from the book
The Woman in Cabin 10 premiered on Netflix on October 10, with Sister producing and Simon Stone directing. The adaptation streamlines internal monologue and focuses on Lo’s credibility on screen. The author has publicly supported these changes. According to a People report dated October 11, Ruth Ware said it was right to alter plot elements to avoid harmful tropes and to serve the medium. She said,
"Often in court cases where women are accusing a man of something untoward, there'll be a lot of discussion about what she consumed, what her mental health history is, what her sexual history is, et cetera, and it's all on the woman to prove that she's actually someone with integrity,"
