Matt Smith is more famous because of his run in Doctor Who, but Claire Foy wasn't exactly some unknown actress.

Foy, 33, won a Golden Globe and two Screen Actors Guild awards for her nuanced portrayal of Britain's monarch in the 1950s and 1960s. (When Smith first started on "Doctor Who" nearly 10 years ago, he signed a three-year, £600,000 contract - just over $1 million in Canadian dollars.) "The Crown", one of the most expensive TV shows in history, had an approximate budget of US$7 million an episode.
Foy played Queen Elizabeth in the drama from showrunner Peter Morgan, Sony Pictures Television Studios and Left Bank and earned a Golden Globe, SAG Award and Emmy nomination, among other accolades, for the part.
While the series will lose Foy and Smith, they've picked up Helena Bonham Carter to play Princess Margaret. Most recently, it was revealed that Michelle Williams made virtually nothing in comparison with her "All the Money in the World costar Mark Wahlberg, despite their near-equal star status".More news: Cyclone alert for Kerala coast: Heavy rain, strong winds likely
The producers insisted the pay discrepancy would be changed for future seasons - however, that will be of little consolation to Foy, who will no longer star in the show.
Foy made $40,000 per episode, Variety revealed past year. New actors are being brought in to take over Foy and Smith's roles, among others, for the previously announced third and fourth seasons with those parts being recast for what is expected to be a fifth and sixth season.More news: There are 7000 pairs of shoes outside the Capitol.
