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.
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.
When Camille leaves work, she plugs in her smart phone and precedes 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.
Sophia Lillis, who plays the younger version of Amy Adams's character, also plays the young Beverly Marsh in the film adaptations of Stephen King's "IT" by Andy Muschietti. Amy Adams was a fan-favorite to play the adult Beverly Marsh before Jessica Chastain was cast in the role.
Amy Adams and Chris Messina previously starred together in Julie & Julia (2009), where they played husband and wife. Adams suggested Messina for this role, because they remained friends after the movie.
The music of Led Zeppelin features quite symbolically in Camille Amy Adams' life throughout the series. Coincidentally, the band's "Good Times Bad Times" also featured on the soundtracks of both The Fighter (2010) and American Hustle (2013) in which Adams also starred.
In episode 'Closer' the residents celebrate Calhoun Day. As the play commences they hoist a painted banner which says 'Calhoun Day'. If you watch slowly just before the banner drops, the text changes to say 'Shallow Day'.
Adora is revealed to have been poisoning her otherwise-healthy daughters to make it appear that they were sick and ultimately dying. As is mentioned in the series, this means she has a mental condition called "Munchausen syndrome by proxy," in which a parent or other caregiver fakes a the illness of a child or other patient to benefit from the societal prestige of being a selfless and dedicated caregiver to a critically ill person. While this is a real mental condition, it is arguably much more represented as a plot contrivance in fiction than in real life. Munchausen syndrome by proxy has been a popular plot twist on many TV shows, including The X-Files, ER, Body of Proof, The Practice, House, Law & Order, Law & Order: SVU, Criminal Minds, JAG, Elementary, and Supernatural; in the horror or mystery novels It and Misery (both by Stephen King), The Body Farm by Patricia Cornwell, and the source for this series, Sharp Objects by Gillian Flynn; and in the movie The Sixth Sense.
In the episode Falling, in the scene where Camille calls her boss while having an emotional breakdown, there is a sign over a store in black letters on white background ahead of her that says Queasy. When she ends the call and starts to drive off, the sign has changed to say Engli- (rest of the word hidden).
This is the second series by director Jean-Marc Vallée that uses a song from Danish musician Agnes Obel's " Aventine" album . Vallée had previously directed " Big Little Lies," which contained Obel's " September Song". Sharp Objects used a song from the same album in the premiere called " Chord Left".
