Christina Ricci created the series after reading Therese Anne Fowler's novel. However, executive producers Dawn Prestwich and Nicole Yorkin discarded most of Fowler's novel and instead took a wide latitude when adapting the source material. Drawing on outdated biographies, the series promotes many debunked myths about the Fitzgeralds' romance and Zelda's life in the Jim Crow South. Scholars affiliated with the F. Scott Fitzgerald Society described it as "more fantasy than fact."
According to executive producer Nicole Yorkin, the series writers knew very little about the Jazz Age, and the production company asked a UCLA professor to give them a crash course on the subject. Given the limited time, much of the show's depiction of the era is historically inaccurate. Many songs heard were either written or performed a decade later in the 1930s. Many actresses wear brassieres at a time when few women did so. Its depiction of a 1918-1919 Jim Crow South with harmonious race relations at a time when race riots and violent lynchings paralyzed major Southern cities like Montgomery is highly inaccurate.
Although purportedly based on Therese Anne Fowler's novel "Z: A Novel of Zelda Fitzgerald", the series features little dialogue and scenes from the book. According to the executive producer Dawn Prestwich, the show's writers jettisoned all of Fowler's work. "A book is not a script, as everybody who has ever tried to adapt one discovers," Prestwich stated in an interview. Drawing from a hodgepodge of sources, the series creates a quasi-mythical depiction of the lives of Zelda Fitzgerald and F. Scott Fitzgerald.
The series was criticized for the ages of the lead actors in comparison to their historical counterparts. A 36-year-old David Hoflin portrayed 21-year-old F. Scott Fitzgerald. For her role as 18-year-old Zelda Fitzgerald, 35-year-old Christina Ricci's features had to be digitally altered to make her appear like a teenager. Critics noted that Ricci was the same age as Zelda when she appeared in La leyenda del jinete sin cabeza (1999), nearly two decades earlier.
On April 27, 2017, Amazon ordered a second season. Later that same year, Amazon canceled the TV show after one season. In 2020, Christina Ricci revealed the show was canceled when one of its executives was accused of sexual harassment, prompting Amazon to cancel all his projects.
