Netflix officials have halted production on The Crown a day early due to an on-set outbreak of Covid-19.
Filming of the fifth series was halted on Wednesday after at least eight crew members tested positive, a source told the Daily Mail.
Netflix representatives subsequently confirmed the news in a statement, which read, "The Crown finished filming one day earlier than planned for the Christmas break following a few positive cases."
The U.K. has been severely hit by the Omicron variant of the virus, with mass entertainment including West End shows and football games cancelled or postponed as a new wave of the disease has taken hold.
The coronavirus outbreak on the set comes after Bertie Carvel and Lydia Leonard filmed their first scenes as Tony Blair and his wife Cherie. The fifth series of the show, which will focus on the collapse of Prince Charles and Diana's marriage and the lead-up to her subsequent 1997 death, is scheduled to air next November.
The new season will mark Imelda Staunton's first appearance as Queen Elizabeth II, taking on a role previously played in different eras by Claire Foy and Olivia Colman. The star-studded cast also includes Dominic West as Prince Charles, Elizabeth Debicki as Princess Diana, and Jonathan Pryce as Prince Philip. Lesley Manville will play the Queen's sister, Princess Margaret.
Season five was originally supposed to be the final instalment of the show, but creator Peter Morgan has since confirmed the royal drama will conclude with a sixth series.
