Claire Foy has said she was "very upset" that she got paid less than her The Crown co-star.
She said it was "heartbreaking" discovering Matt Smith was paid more for her but subsequently it has had an "amazing impact".
The 38-year-old’s performance as a young Queen Elizabeth won her two Emmys and a Golden Globe, however in 2018 producers revealed it earned her less than Smith’s portrayal of the Duke of Edinburgh.
