This 2023 documentary, directed by Errol Morris, is an in-depth interview with the renowned British author of espionage thrillers, David Cornwell, better known by his pen name John le Carré.

You may not be familiar with the name David Cornwell, but most people have heard of John le Carré, bestselling author of numerous spy thrillers, many of which are considered masterpieces of the genre.

A former British intelligence agent himself, le Carré adopted his pen name on the publication of his first novel, which introduced his unlikely hero George Smiley.

In The Pigeon Tunnel, director Errol Morris interviews le Carré about his life and career, covering his turbulent relationship with his fraudster father and the impact of his mother's disappearance when he was young.

Themes of betrayal and lies, which loom large in both le Carré's life and novels, are ever present in this portrait of the enigmatic writer.
