Because Michael Jackson's sole has such a design, it can fix his feet, and then the center of gravity of the whole body leans forward, and all the stress points are supported by waist strength.
In the original film, Michael Jackson leans forward with a rope around the actor's waist. Of course, the rope is post-processed by MV, which is invisible to the audience.
The angle at which an actor leans forward depends on the mechanical control of the ceiling. At that time, you can even see the forward rotation of 45 degrees in the MV. It was unrealistic to do so later, because there was no time to dismantle the waist design. Finally, we decided to use dazzling stage lights, smoke generators, lasers and dancers as a cover to distract the audience and buy time for MJ. When MJ is ready, the "special area" will be lit up. Mike fell 45 degrees before, and it was successfully realized.

Technical details—
This method overcomes the shortcomings of the rope system and can make the concert go on coherently. So as to achieve the visual effect that the center of gravity of the body exceeds the support point. At the same time, the "grappling hook" system of the stage can be extended and retracted accurately and timely through the control of precision instruments, so as to achieve the purpose of not being discovered.
Special reminder: Even so, this action is not something that ordinary people can do, because to complete this incredible action, apart from advanced instruments, it is also inseparable from the hard exercise, careful rehearsal and running-in of Michael and the actors. Can not do without strong back muscles and body balance control!
