Remember the dream sequence from Inception, where the actors were falling all over the place because the gravity seemed to be shifting? Apparently it was super difficult and complicated to make, and it required a giant man-made hallway that could rotate at a precise speed.
As this video points out it took a ton of work to make one of Nolan’s most complicated set pieces. Instead of using a plane or CGI to achieve a “zero G” look, Nolan just built a giant set and spun it.
And then Joseph Gordon-Levitt and the other extras had to train for weeks to master the stunts they would be pulling before they could film.
What’s great about this “Art of the Scene” by Cinefix is that it points out just how much work goes into making a scene such as this one. And as the video mentions, it wasn’t even a very critical scene, but still they put in as much effort as they could to make it look excellent. They could’ve thought of how difficult it would be to pull off this idea, but they didn’t. I found this to be a good inspiration to not give up on an idea, but instead looks for ways to make your idea work.
