Spencer: Kristen Stewart's wigs in Pablo Larraín's directorial cost $12,000 to make

Kristen Stewart's performance in Spencer and Pablo Larraín's filmmaking is being lauded ever since the film made the rounds in festivals. But what probably went unnoticed was the effort and resources that took to transform the actor into Princess Diana.

In a recent interview with InStyle magazine, hair and makeup designer Wakana Yoshihara spoke about the exorbitant amount it took to create two wigs for Stewart, and how long they took to perfect. Yoshihara has previously worked on films like Kenneth Branagh’s Cinderella, Pedro Almdóvar’s The Human Voice, and Ben Wheatley’s High-Rise.

"This process took about six weeks, and I probably colored the wig three times before I met Kristen. When we did the first fitting I knew the color wasn’t right, so I colored it again. In the beginning, [Stewart] didn’t want to wear a wig, I think because she didn’t have experience wearing a very good wig. Then she put this one on, and with the makeup, we got great feedback. She was very happy and confident with it," told the magazine.

Every wig, Yoshihara said, cost $6,000 to make after many revisions in colour, length, and quality. The hair designer revealed that while Diana's hair was more on the honey blonde, Stewart's wig was coloured an ash blonde to suit her complexion better.

Stewart is among the many actors that have portrayed the Royal on screen with the latest one being Naomi Watts in Diana (2013), and Elizabeth Debicki in the upcoming fifth season of Netflix's drama The Crown. 

Spencer takes place over three days of Diana's stay Queen's Sandringham Estate to celebrate Christmas when all eyes are on her and Charles' crumbling relationship. While Stewart plays the titular role, Farthing is Prince Charles, Spall is Equerry Major Gregory, Harris is Chef Darren, and Hawkins is Maggie.
