"The Pigeon Tunnel": Errol Morris Unveils John le Carré's Intriguing Life

In his latest film, "The Pigeon Tunnel," documentarian Errol Morris engages in a duel-like interview with renowned spy novelist David Cornwell, better known as John le Carré. The film explores their complex relationship and delves into Cornwell's life and career as a writer of espionage novels. While the documentary is enjoyable and brisk, it falls short of delivering a definitive revelation or conclusion, resulting in a draw between the two participants.
