One small click: that's all it takes. It’s the difference between life and death. Between action and indifference. Between a lack of supplies and that one small thing that can save a child's life. That became the simple idea behind this film for Doctors Without Borders, which encourages viewers to make that tiny difference—and “click”.

We shot it in a studio and the challenge was to make it not feel like a studio outside the tent. So with some subtly moving lights and wind I think we succeeding in making it feel like it was a world outside the tent.

It was a very technical job. My first time working with motion control. People had warned me that it’s a very slow tool but it was so much slower that I had imagine. We short everything in one very long day and had to compromise and rush a lot to get what we needed. But we happily did.
