Excellent New Yorker article about the original BBC version of John le Carre’s Tinker Tailor Soldier Spy and its sequel, Smiley’s People, both starring Alex Guinness as George Smiley. Both of these are incredible and faithful six part adaptations and I’ve probably seen each one at least six times, and read the books twice (including the middle book in the trilogy, The Honourable Schoolboy.) Highly recommended, in spite of le Carre being virulently anti-American.
