Behind Joey King's Beauty Transformation For Hulu's "The Princess"

King had not one but two stunt doubles, both of whom needed wigs that looked identical to the star's extensions. "It was tricky because we have to dye the wig exactly the same color," Armstrong says. "And sometimes working in another country makes everything quite difficult. So to find all these things in Bulgaria was quite hard. I had to get a lot of stuff shipped out from England."

Needless to say, it was a lengthy preparation process but well worth it in the end. Because the wigs could be placed on as a single piece (rather than individually placing extensions), the hair team could cut down on the time it took to get the actors ready each day.
