7. Bruce Willis & His Rubber Feet
I'm sure a lot of you remember the above scene of John McClane pulling razor-sharp shards of glass out of his feet after appearing to run through it barefooted when Hans and his men shot the glass partitions in the computer room. This prompted a very ugly scene of McClane dragging himself into a bathroom bleeding profusely all over the floor before taking part in some DIY surgery. Though Willis appeared to be barefooted, he was actually wearing some specially made rubber shoes designed to look like his feet. They're noticeable in scenes where his feet appear to be unnaturally large, and are hardly inconspicuous to the well-trained eye.
