If you have watched Inception, you would know one of the most iconic scenes in the movie is the corridor fight.
In the midst of a high pursuit chase through a city, Joseph Gordon Levitt’s character engages in battle in a hotel lobby where the gravity is constantly shifting.
If you thought it was achieved with CGI, you are wrong.
According to Viral Thread, the sequence was made possible through the use of an enormous rotating set.
The massive set was made out of seven steel rings, conected to huge wheels that were powered by electric motors and were computer controlled so the crew could turn it clockwise or anticlockwise.
The cameras were mounted onto the set to maintain the illusion of shifting gravity as well as held by a special crane that could telescope deeper into the set.
Levitt trained extensively with the stuntmen before filming began to get used to the constantly changing ground.
Levitt came to terms with the constantly changing ground and shared:
“I had to think of it as ‘this is the ground’. Okay, now this is the ground. Okay, now this is the ground, each time it changed."
