The song was released on 1988, and the 45-degree tilt seen in the MV is a rope around the actor's waist. Of course, the rope is post-processed by MV, which is invisible to the audience. This method is not realistic at the concert. Because the rope tied to the waist is impossible to install and disassemble in live performances. Secondly, the pre-installed rope limits the dance movements of the actors' arms and bodies. So Jackson and his assistant invented a special pair of shoes. 1993, Michael applied for a patent, and the patent number was surprisingly 45 degrees forward (US5255452). The patent name is "Get rid of the illusion of gravity". When Mike needs to perform stunts, MJ will be close to the "special area" of the stage with the dancers. Usually, the lights in this area will be very dim. The "gangster" played by the staff will immediately take the stage and perform with explosives for a few seconds. Distract the audience and buy MJ time to prepare. When MJ is ready, the "special area" will be lit up. Mike leans forward 45 degrees in one go! ! The key detail lies in MJ's special shoes. As can be seen from the figure, the heel is mechanically connected with the stage, which can firmly fix the body support point. 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 Mike and the actors. Can not do without strong back muscles and body balance control!
