Royal Slip-Up: This 'The Crown' Star Accidentally Just Revealed the Season 3 Premiere Date

Keeping something as exciting as the release date for the next season of Netflix's The Crown quiet seems to be just as difficult as keeping an actual royal's whereabouts on the DL.

Outlander's Tobias Menzies, aka the new Prince Philip, will take over the role for The Crown in season three from the artist formerly known as Prince Philip, Matt Smith. Menzies appeared on BBC Radio last week, and spilled the royal tea about season three's premiere date.

“We shot season three and that starts in November,” Menzies said on Jo Good‘s BBC radio show. As in November 2019. Yes, cue a royal freakout.

The third season, which has been in production for close to a year, released the latest photos from the set, starring its new Queen Elizabeth, Olivia Colman, back in December 2018. The second season premiered in December 2017.

This update is the most concrete confirmation of when we can expect new episodes of the period drama.

In mid-June, actress Erin Doherty, who will portray Princess Anne, said she "believes the new season will be out in the autumn,” according to The Irish News via the Express. Previously, Netflix had revealed (in a letter to investors) that the show's third season would be out in the "second half" of 2019.

One of the reasons we're panicking over every little detail that's spilled about season three: The cast is absolutely incredible. Besides Colman, who won the Oscar for Best Actress this year for her role in The Favourite, we'll see Helena Bonham Carter take over for Vanessa Kirby to play the rebellious Princess Margaret.

Josh O’Connor (Florence Foster Jenkins) and Marion Bailey (Allied) will take on the roles of Prince Charles and the Queen Mother, respectively, while Pennyworth's Emma Corin will play a minor role as Princess Diana in season three (and take on the much bigger role in season four, when Diana is being courted by Prince Charles). Call the Midwife's Emerald Fennell will play Camilla Parker Bowles.

The one addition to the cast we're most excited for, though, is Sex Education's Gillian Anderson as "Iron Lady" Margaret Thatcher.

Mark thy royal diary: The Crown season three premieres on Netflix this November.
