To give the illusion of being freaks, the appearance of several actors was modified by make-up elements. John Fleck (Gecko) spent over ten hours in makeup each day to transform into and out of his character. The skin, which needed to look like alligator hide, consisted of seven or eight separate pieces and needed to be glued to Fleck's face.[88] Patrick Bauchau (Lodz) had several contact lens pairs of different opaqueness.
