Agent Zeta Becomes One of Prime Video's Most-Watched Non-English Originals

Agent Zeta, Prime Video's Spanish-language action thriller directed by Dani de la Torre and starring Mario Casas, has climbed the streaming charts since its March 20, 2026 release and emerged as one of the platform's most-watched titles. The film follows a former assassin called back into action after four Spanish ex-intelligence officers are assassinated simultaneously worldwide.

The Centro Nacional de Inteligencia links the killings to veterans of "Operation Ciénaga" in Colombia, and Zeta is tasked with hunting down and protecting the sole survivor. The cast also includes Luis Zahera, Mariela Garriga and Christian Tappan. Agent Zeta now ranks ninth among Prime Video's non-English original films from Amazon Studios, appearing alongside titles such as Vengeance and the Culpa franchise, while the legal drama System holds the top spot on the list.

Critical reaction has been mixed.
