Black Box (French: Boîte noire) is a 2021 French-Belgian mystery thriller film directed by Yann Gozlan.

The film stars Pierre Niney as a talented young black box analyst at the Bureau of Enquiry and Analysis for Civil Aviation Safety who is tasked with investigating a mysterious fatal plane crash.

A pilot tells Mathieu that the Atrian 800 had unresolved problems with the rudder's anti-stall system, but still received an air-worthiness certificate.

Mathieu surreptitiously downloads the relevant test flight data from a computer belonging to his wife, Noémie, who works for Atrian.

Mathieu persuades Rénier to use the flight data to run simulations on the anti-stall system, but these fail to reveal any problems.

An investigative journalist from Mediapart, Caroline Delmas, tells Mathieu about a man named David Keller, a former Pegase employee who was arrested for attempting to hack an aircraft's communication systems.

Director and co-writer Yann Gozlan is a civil aviation enthusiast and had wanted to make a film on the subject for a long time: "This universe, incredibly cinematic from my perspective, with colossal financial stakes, where divergent interests co-exist (aircraft manufacturers, airlines, pilots...), seemed to me like an original and exciting setting for a film".
