Fox 21 Television Studios has elevated veteran production executive Nissa Diederich to EVP Production.

In her expanded role, Diederich will assume oversight of all production matters on the company’s series, ranging from American Crime Story, Homeland, Queen of the South, Genius and The Chi, to the upcoming Pose, Mayans, The Politician and Ratched. Additionally, Diederich will continue to oversee the productions of 20th Century Fox TV’s American Horror Story and 9-1-1. She’ll be responsible for working closely with the studio’s showrunners to secure stages and locations, hire crew, manage budgets and supervise the production process from pre- to postproduction. Diederich will continue to report to Bert Salke, President.

“Nissa has overseen some incredibly ambitious productions, from seasons of Homeland overseas in South Africa and Berlin and Genius in Budapest, to the multiple series of the prolific Ryan Murphy, and she is beloved by creators and executives alike,” said Salke. “She has been enormously helpful to Mark Pearson and me as we’ve grown the Fox 21 TVS business, and we consider ourselves fortunate to have such a seasoned pro in this vital role.”

Diederich joined the former Fox Television Studios 20 years ago as a Manager of Production Finance, rising through the ranks to oversee all aspects of production finance for primetime network, cable, international and alternative television production for Fox Television Studios, Fox World Productions, Regency Television and The Greenblatt Janollari Studio. Most recently serving as SVP Production at both Fox 21 Television Studios and 20th Century Fox Television before that, Diederich oversaw the productions of Ryan Murphy’s Glee, American Horror Story, American Crime Story and Feud, Kurt Sutter’s Sons of Anarchy and upcoming Mayans and Alex Gansa’s Homeland.
