Honestly, I am allergic to the idea that everything is just vague inspiration from fiction; it seems like pure media hype.
In real life, a tourist guide, especially when in Tunisia, is what changes the concrete of the trip, not just an appendix to a film.
For example, when in the desert without network, it’s not a novel that tells us where to find water, but the printed guide we brought.
What matters is what changes tomorrow on the ground, not glossed dreams.
