Interview:
One of the first things I did was to work up a costume. A vital, visual part of the character. I had to know how he looked ... before I did any breakdowns. For example: A clinging power so he wouldn't have hard shoes or boots, a hidden wrist-shooter versus a web gun and holster, etc. I wasn't sure Stan would like the idea of covering the character's face but I did it because it hid an obviously boyish face. It would also add mystery to the character.
