Black Box

Black Box (Boîte noire, 2021) is a French thriller you can watch online on iFILM, directed by Yann Gozlan. Aviation safety analyst Mathieu is handed what looks like a routine assignment: examine the flight recorder data from a crashed passenger jet and determine the cause. Two hours of audio. Standard procedure.

What he hears on that recording doesn't match what anyone else is prepared to admit. When his superiors pull him off the case, he keeps digging on his own time. Pierre Niney plays Mathieu as a man whose professional obsessiveness becomes indistinguishable from paranoia — which is exactly the tension the film exploits. You follow the clues alongside him but can't fully trust his interpretation, and that uncertainty holds for most of the film's 129 minutes. For viewers who like procedural thrillers where the conspiracy earns its reveal rather than announcing it early. Stream Black Box (2021) online on iFILM.
