Premieres Sundays, Oct. 5 and 12, 2025 at 8 p.m. on KPBS TV / Stream with KPBS+. 1989. When two old friends - the “much feared inquisitor” Brian Walden and “Iron Lady" Margaret Thatcher - come together for their last-ever TV interview, little do they realize they're about to embark on one of the most famous political exchanges of all time. Helmed by Steve Coogan as politician-turned-journalist Brian Walden and Harriet Walter as Prime Minister Margaret Thatcher, this drama recounts the end of a political era and a long-term friendship.
