“In Errol Morris’s documentary, the sense of getting nowhere in particular proves to be crucial toward grasping John le Carré in all his impish glory.” ~ Keith Uhlich, Slant Magazine
“Through it all is the tension of whether one can truly know le Carré, a man who first made a living hiding his true self, and then another living as a writer delving into it. Morris captures that paradox… quite perfectly.” ~ David Sims, The Atlantic
“An interrogation of art and artist, The Pigeon Tunnel is an enthralling documentary both for fans of le Carré and those who’ve never read a page of his work.” ~ Barry Levitt, Empire Magazine
“Errol Morris’s biographical documentaries have got to the heart of figures ranging from Stephen Hawking to Donald Rumsfeld, but in John le Carré he has found a subject as unknowable as he is eloquent.” ~ Jake Kerridge, Daily Telegraph
“The result is a wide-ranging dialogue that manages to be both philosophical and playful, a personal portrait that goes exactly as deep as Cornwell wants it to go but never feels as if the author is getting away with obfuscation.” ~ Steve Pond, TheWrap
“He’s a grand chronicler of his own biography, and expertly goaded on by Morris, whose queries challenge present and past statements and compel further elaboration and contemplation.” ~ Nick Schager, The Daily Beast
