Whilst, with other TV shows, it might be possible to spin a tale about the male character actually being the more significant and demanding role, in this case, feminists have been able to adopt the straightforward argument that, "She was The Crown". Sure, we've got a female Doctor now, but when Matt Smith was cast, Dr Who had essentially been a long-running sausage-fest.
Before her role on "The Crown", Foy appeared in several episodes of United Kingdom drama series "Upstairs Downstairs" and played Anne Boleyn in the Emmy-nominated "Wolf Hall" miniseries.
It is not known what Smith was paid for the series.
However, given that Smith's role as Prince Philip was less central to the narrative than Foy's as Queen Elizabeth II, many viewers have been outraged by the revelation.
However, even if the pay gap is remedied in future seasons, it won't benefit Foy, whose work on the series is over.

The Crown co-producer Suzanne Mackie told a television industry conference in Jerusalem that the pay difference would be rectified. She was also nominated for an Emmy for her season one performance.
Mark Wahlberg made $1.5m (£1.1m) but donated it to Time's Up, following news that Williams had received less than $1000 (£720) for her work.
"Going forward, no one gets paid more than the Queen", Mackie said, pledging that season three with Olivia Colman will be different.
Representatives for Smith and Foy did not respond to CNN's multiple requests for comment.
Actress Michelle Williams was revealed earlier this year to have been paid a fraction of what her co-star earned for re-shooting scenes in All The Money In The World after Kevin Spacey was replaced by Christopher Plummer.
