For “One two three, vive l’Algérie” I use a DIY air powered device that creates the illusion of a bloody gunshot impact on buildings in Algiers, Algeria.

The first documented use of squibs to simulate bullet impacts in movies was in the 1955 Polish film Pokolenie by Andrzej Wajda, where for the first time audiences were presented with a realistic representation of a bullet impacting on an on-camera human being, complete with blood spatter. The creator of the effect, Kazimierz Kutz, used a condom with fake blood and dynamite.
