"Contrechamp" on Lemonde.fr

I have recently discovered this bimonthly series of 2-minute videos published on the website of the french newspaper Le Monde (only available in French language, sorry).
The title of the series is Contrechamp (Reverse shot) and its description is as follows:
"Shooting techniques, hidden references, forgotten trends... every two weeks, "Contrechamp" focuses on those small tricks that make great cinema."
The first episode that you can find below is about the famous Wilhelm scream, and you can find all episodes on the website of Le Monde:
