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.
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.
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.
