How were gravity fight scenes in inception filmed by Christopher Nolan

The zerogravity hallway fight scenes were achieved by using rotating sets that twisted and turned and forced GordonLevitt to maneuver with utmost caution. Fivehundred crewmembers were involved in the scene, which took a full three weeks to 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).
