Staunton made the reveal in a recent interview with BBC Radio 2 host Zoe Ball. "There will be the final film - there you go," Staunton declared. Ball then said that she hopes that the star won’t be reprimanded for revealing the info. "I don’t care," Staunton bluntly said. "The Sun" reported Wednesday that the cast will begin shooting this summer at Highclere Castle in Hampshire, England, for a 2025 debut.
