Before she was even a household name, author Stephen King said of Flynn's first book "Sharp Objects" in 2006, "I found myself dreading the last thirty pages or so, but was helpless to stop turning them."
Australian actress Eliza Scanlen makes her American debut as Amma, the half-sister of Camille (Amy Adams). Eliza who'd provided an audition tape from her hometown Sydney, was later flown to the U.S. to screen test with Amy for director Jean-Marc Vallée. Of Amy's kindness to her on set Eliza has said that, "She really took me under her wing," this being her first major role in a foreign country.
When Camille leaves work, she plugs in her smart phone and proceeds to listen to Led Zeppelin. This makes the show a rarity as Led Zeppelin rarely allow their catalog to be played, most expensive to get rights to use, makes it a rarity.
Gillian Flynn's book "Sharp Objects", on which this series is based, was written before "Gone Girl" and took 12 long years to reach the screen. The author has said of her debut novel that it's the book most of her readers ask her about at book meetings and on social media.
Amy Adams lowered her voice timbre for her character Camille as she did not want to sound like an earlier character Giselle with a drinking problem.
