‘Citadel: Diana’ Trailer: Prime Video’s Italian Installment Stars Matilda De Angelis as an Undercover Agent Behind Enemy Lines

Prime Video has released a high-octane trailer for its spy series “Citadel: Diana,” starring Italy’s Matilda De Angelis (“The Undoing”) as Diana Cavalieri, an undercover Citadel agent fighting against an enemy syndicate set in a near-future Milan. The six-episode show – which marks the streamer’s most ambitious Italian original to date – is the country’s installment of Prime Video’s high-concept “Citadel” franchise that debuted in April 2023. The series is meant to serve as a launch pad for multiple shows set in different countries that are all connected via plot and characters. De Angelis, a rising Italian star, made her international breakthrough in Susanne Bier’s “The Undoing,” alongside Nicole Kidman and Hugh Grant. She also appeared with Liev Schrieber in the Ernest Hemingway adaptation “Across the River and Into the Trees,” directed by Paula Ortiz.
