: Morris utilizes his signature "Interrotron" interview technique, complemented by rare archival footage, dramatized vignettes, and clips from iconic film adaptations like Tinker Tailor Soldier Spy .

Errol Morris employs his famous —a device that allows the subject to look directly into the camera lens while seeing Morris’s face, creating an intense, confessional eye-contact with the viewer. The film is almost entirely le Carré speaking, intercut with re-enactments (a Morris specialty), archival footage, and abstract, moody cinematography by Igor Martinović.
