The Battle of Algiers (Italian: La battaglia di Algeri; Arabic: معركة الجزائر; French: La Bataille d'Alger) is a 1966 war film based on occurrences during the Algerian War (1954–62) against the French government in North Africa, the most prominent being the titular Battle of Algiers. An Italo-Algerian production, it was directed by Gillo Pontecorvo and shot on location. The film, which was shot in a Rossellini-inspired newsreel style—in black and white with documentary-type editing—is often associated with Italian neorealism cinema. Wikipedia
Col. Mathieu: We need to have the Kasbah at our disposal. We have to sift through it and interrogate everyone. And that's where we find ourselves hindered by a conspiracy of laws and regulations that continue to operate as if Algiers were a holiday resort and not a battleground. We've requested a carte blanche, but that's very difficult to obtain. Therefore, it's necessary to find an excuse to legitimize our intervention and make it possible. It's necessary to create this for ourselves, this excuse. Unless our adversaries think of it themselves, which seems to be what they're doing.
