‘The Undeclared War’ Season 2 First Look: Simon Pegg Takes Center Stage in Peacock Trailer
The Undeclared War is finally returning to television after four years as Simon Pegg and company prepare to launch Season 2 of the Peacock Original, and we have an exclusive first look at the action to come.
For those who may need a refresher, Season 1 of the drama revolved around GCHQ, otherwise known as Britain’s National Security Agency. When the organization is foiled by a country-crippling Russian cyber attack, GCHQ realizes there’s more to come. Season 1 introduced viewers to the world through Saara’s (Hannah Khalique-Brown) point of view as a work-study newbie, and Season 2 shifts its point of view to Head of Operations at GCHQ, Danny (Simon Pegg).
The exclusive first look at Season 2 teases more drama ahead for Danny, Saara, and more as we unveil the official trailer above. The Undeclared War will officially return for Season 2 on Thursday, August 27, as all six hour-long episodes drop on Peacock for fans to stream.
