To create the illusion of low gravity, director Irving Pitchel attached the actors to piano wire run through a pulley system and controlled by an overhead crane.

为了营造低重力的错觉，导演欧文·皮切尔将演员连接到通过滑轮系统运行的钢琴线上，并由桥式吊车控制。

He could remember how the overhead crane man had shouted He-e-eads up! as he had sailed down the length of the building with the first load of the parts dangling from his hook.

他还记得当时头顶上的起重机指挥者叫嚷着小心，起重机钩子上悬挂着第一批零件，将零件放在建筑上。
