Caesar Flickerman (played by Stanley Tucci) and his powder blue wig. Petenbrink says they ordered an extremely expensive (think thousands of dollars) hand-made wig custom fitted to his head. But when it arrived it wasn’t the perfect shade of powder blue. So Petenbrink and three assistants had to alter the color — extremely carefully.

“I couldn’t get any dye on the base of the wig, since that would have made him look like he had a blue scalp, and I couldn’t get any on the strands of hair we didn’t want colored,” she says. “I worked in very small sections, just washing things out in a little sink with three assistants for the entire day. Nothing could go wrong; it was the only wig they had for him and the shoot was starting soon. There wouldn’t be time to get a new one if I messed up.” Luckily, they got the job done.
