De acordo com o diretor do filme, as torres gêmeas Eiffel foram projetadas para servir como o pórtico para um terminal de teleférico extenso.
Q. How did you come up with the magical idea for the “cruise liner” suspended on cables that April’s parents used to run away? Are you fascinated by those often far-fetched prototype vehicles that have been invented throughout all periods of history?
I have to say that it was our cowriter Benjamin Legrand who came up with the idea for the Paris-Berlin cable car link, with the double Eiffel Tower serving as a terminus in the French capital. We’ve all seen the Eiffel Tower but the cable car had to be invented, so I went through some back issues of “La Science et la Vie” from the beginning of the century, and found some descriptions of several fascinating mechanical prototypes. I also used old diagrams of steam engines and other inspired contraptions because I wanted the cable car to be credible. It had to be steam-powered, the mechanisms had to turn the wheels using a method similar to that of a bicycle chain, and it all had to work using rack and pinion. It took me quite a long time to make it realistic. And although you can’t really see how it works, I also designed its internal mechanisms. I think the cable car works well in the film, and that you believe in it.
Você pode querer notar que todas as evidências sugerem que esta não é uma segunda Torre Eiffel construída ao lado do original e depois convertida em um terminal aéreo, mas que as duas torres foram construídas juntas para isso. propósito expresso.
