I had this idea 15 years ago, during conversations with crazy friends, Besson says.
Then the next question is, How can we have fun?'
So I came up with the idea of colored stripes on the rocks, which is based on coral.

And no red sand or else it looks like Mars.
If this sounds complicated, Besson understands that.
After I wrote the sequence, I explained it to the crew for an hour, he says.

They were smiling, but I could see on their faces that they didnt understand a thing.
I brought the 120 students to the soundstage and we shot the entire scene, Besson says.
They were the actors, they were the cameramen, the lighting people, the grips.

We put the 600 shots on the wall and one by one we shot them.
They did everything in three weeks, and then we edited and put in some temp music.
Besson adds with a proud laugh, And then the crew understood the scene.
Thus concluding Multidimensional Action 101.
