Not even the queen of England can get an equal slice of the mincemeat pie.

The actress Claire Foy, who charmed critics and fans as a young Queen Elizabeth II in the Netflix series “The Crown,” was paid less than her co-star Matt Smith, who played the queen’s husband, executive producers acknowledged on Tuesday at the INTV Conference in Jerusalem.

Mr. Smith came to Netflix as an established actor in Britain, most notably as the titular character on the BBC staple “Doctor Who” from 2010 to 2013 — a fact that informed the producers’ decision around salary, they said at the conference.

Aside from a role in 2015 in the Golden Globe-winning BBC mini-series “Wolf Hall,” Ms. Foy, 33, was a relative unknown when she was cast in “The Crown.” But in the show’s first two seasons, which centered on her character’s reign, Ms. Foy became its breakout star, earning a best actress Golden Globe for Season 1 and a Golden Globe nomination in the same category for Season 2. She was also nominated for an Emmy for outstanding lead actress in a drama for Season 1. Mr. Smith, 35, was not nominated for an Emmy or a Golden Globe for his role as Prince Philip.

Netflix declined to comment. Representatives for Ms. Foy and Mr. Smith did not immediately respond to requests for comment.
