The refusal by the film department to allow "Smallville" to show Jor-El forced the special effects crew to come up with a creative way to display some sort of aid to help the audience visualize this disembodied voice that was supposed to be talking to Jonathan in "Exile". They decided to create a force field around whoever was speaking to Jor-El, which acted as Jor-El's voice, rippling as he spoke. To save money on this effect, the crew filmed John Schneider on a black backdrop, and Entity FX digitally added the force field around him. Wind machines and a spot light were added to help synthesize the atmosphere in the force field. Another aspect of the Superman mythology appeared in season three's "Hereafter", and was also created digitally: Superman's cape. In the scene, Clark is touched by a boy who sees the moment of someone's death; when he touches Clark he does not see Clark's death but a cape flapping in the wind. Instead of just shooting a practical cape billowing, the scene was developed entirely by a computer. Created primarily by John Hahn, the idea was to show the cape but not so clearly that it would be obvious to the audience what they were looking at. As Beck explains, "You get a hint of the 'S', but not quite."
