“The zero-gravity hallway fight scenes were achieved by using “…massive, rotating sets that twisted and turned and forced Gordon-Levitt to manoeuvre with utmost caution. Five-hundred crew members were involved in the scene, which took a full three weeks to complete.” The sets were built in a London airplane hangar, including a horizontal hallway that rotated 360 degrees, a vertical one and a set with steel trolleys to which the actors were attached by wires (later erased using visual effects).” (YouTube)
Following on from yesterday’s OK Go video with the rotating room, we have a video explaining how it was done in the film Inception. Basically, a massive rotating room and lots of people and practice. It’s a stunning practical effect that is amazing to watch over and over again. Even knowing how it is accomplished doesn’t make it any less impressive; in fact, I’d say it’s even more impressive knowing that it’s not just CGI.
Makes me really want to watch the film again. Onwards!
