Deadline

The three actors are among the cast members on the six-part Channel 4-Peacockseries that will reunite the Wolf Hall team. Written by White Oleander and Wolf Hall director Peter Kosminsky, The Undeclared War "takes place in the post-pandemic world of 2024 against the backdrop of an upcoming British general election involving the UK’s first Black Conservative prime minister (Lester)," per Deadline. "It tracks a leading team of analysts at the heart of the UK’s NSA-style spy agency GCHQ as they attempt to ward off a cyber-attack on the country’s electoral system. Pegg features as Danny Patrick, GCHQ’s head of operations, while Rylance plays John Yeabsley, a GCHQ old hand, who is brought back into the fold to support former colleagues in combatting the heightened threat level."
