About The Diplomat TV Series

In January 2022, Netflix announced that it had given a series order to The Diplomat, created by Debora Cahn. By February of that year, Keri Russell was confirmed as the lead star. In March 2022, Ali Ahn and Rufus Sewell joined the cast, and in April 2022, David Gyasi, Ato Essandoh, Rory Kinnear, Miguel Sandoval, Nana Mensah, Michael McKean, Celia Imrie, and Penny Downie were also added to the cast. The series was released on April 20, 2023.

Filming took place across various locations in the UK and Paris, France. In London, producers were granted permission to film inside the American embassy in Nine Elms and the Foreign Office in Westminster, including The Durbar Court and the Foreign Secretary’s office. Outside of London, Wrotham Park in Hertfordshire served as Winfield House, the residence of the US Ambassador to the United Kingdom, while Ditchley Park in Oxfordshire represented Chevening, the foreign secretary’s country residence in Kent.

Additional filming locations included the Old Royal Naval College in Greenwich, Cotswold Airport in Gloucestershire, and London North Studios in Mill Hill, where sets for The Oval Office and US Embassy were constructed. In Paris, scenes were filmed at the Palais-Royal and the Louvre, including the Pyramid and Escalier Daru.

On May 1, 2023, Netflix renewed The Diplomat for a second season, which began filming in June 2023 at locations such as St. Paul’s Cathedral. Other filming sites for the second season included the Old Royal Naval College, One Great George Street, Inveraray Castle, Ardkinglas, RAF Halton, Wilton House, and Blenheim Palace.

In January 2024, it was announced that Allison Janney had been cast as US Vice President Grace Penn for season two. The second season was released on October 31, 2024. Ahead of the second season’s premiere, Netflix renewed the series for a third season on October 10, 2024. On January 24, 2025, Bradley Whitford was cast as Todd Penn, the husband of Grace Penn for season three.

Season 1 featured in the global Netflix top 10s for four weeks, picking up 173.46 million hours watched. The season featured in the Nielsen top 10 charts for two weeks in the US picking up 44.90 million hours watched.

Title conflict

The choice of title reportedly caused frustration among the British producers of a Barcelona-set series also titled The Diplomat, which was announced in early 2020 and began airing in the UK two months before the Netflix series. Neither party has indicated a willingness to change the title to avoid confusion.

The Diplomat Release Date

The Diplomat premiered on Netflix on April 20, 2023. In May 2023, it was renewed for a second season, released on October 31, 2024. In October 2024, the series was renewed for a third season that its Facebook advertizement states will premiere in 2025.
