VIDEO : 'The Crown' Actress Talks Going From Blonde to Brunette

'The Crown' star Claire Foy recently revealed she's discovered a major difference after she went from being a blonde to a brunette. While on 'The Tonight Show Starring Jimmy Fallon' this week, Foy explained that when her hair was a cream soda blonde, "People just nicer to you. People hold the door open to you. They smile at you, just in general.? The dramatic change isn't entirely due to preference as Foy has reportedly changed up her hair for roles in the upcoming Neil Armstrong biopic 'First Man', and the sequel to 'The Girl With the Dragon Tattoo'.
