The Amazon Prime Video series Citadel had multiple directors across its episodes, as is common for television series. While individual episodes were directed by various talents, the overarching creative vision and executive production were heavily influenced by a core team.
For the initial episodes, Newton Thomas Sigel directed the first two, and Jessica Yu directed others. However, the series was developed by Josh Appelbaum, Bryan Oh, and David Weil, with Weil serving as the showrunner. The Russo Brothers (Anthony and Joe Russo) were also key executive producers, driving the global spy thriller's ambitious scope and interconnected universe.
Therefore, while specific individuals directed episodes, the creative direction of Citadel is more accurately attributed to its showrunners and executive producers who shaped the entire season.
Pro tip: For most TV series, look to the showrunner and executive producers for the primary creative vision, as individual episode directors often execute that vision rather than defining it entirely.
