One transformation that surprised us the most was that of Meryl Streep, who played her part wearing a deep red pixie cut. It's a stunning change, though it's one that the actress and her own personal hairstylist came up with on their own.
"Meryl has this amazing gentleman, Roy, who's looked after her for many, many, many years, and he does her hair and makeup," Clark said. "He's responsible for Meryl, and that's a decision that Ryan and Meryl and Roy came to. He's been her hair and makeup designer for decades, and they do brilliant work."
