*Warning: Spoilers ahead*

Season four of The Crown has officially dropped and fans already have a lot of thoughts. In fact, it's sparked a number of discussions about the accuracy of the show—especially when it comes to Prince Charles and Princess Diana. But since the season has ended on quite an interesting note, royal fans are now even more eager to learn about what's in store for the show's fifth season.

Who will be returning to the cast? How many new characters will be added? And most importantly, when can fans expect to see the first trailer? See below for details on what we know so far about The Crown season five.

1. What will season 5 of 'The Crown' be about?

The plot hasn't been confirmed yet, but since the season four finale ended with Margaret Thatcher's resignation in 1990, season five will continue with her successor, John Major.

Major served as Prime Minister of the U.K. from 1990 to 1997, which proved to be a pretty scandalous time period for Prince Charles and Princess Diana. In that time, the Princess of Wales's biographer, Andrew Morton, published his controversial book, Diana: Her True Story. We also know that the princess divorced Prince Charles and moved on to date a heart surgeon before her tragic death in 1997.

In short, fans can expect to see quite a bit of drama unfold in season five.

2. Who will be cast in the new season?

The season five cast will look quite different because it will feature older versions of the royal family.

Emma Corrin will be passing the mantle on to Elizabeth Debicki, who will star as the new Princess Diana, and Dominic West will be filling Prince Charles's shoes, instead of Josh O'Connor.

Meanwhile, Harry Potter actress Imelda Staunton will follow Olivia Colman in the role of Queen Elizabeth, Lesley Manville will succeed Helena Bonham Carter as her sister, Princess Margaret, and Jonathan Pryce will succeed Tobias Menzies as the queen's husband Prince Philip.

In an interview with Deadline, series creator Peter Morgan said, "I’m absolutely thrilled to confirm Imelda Staunton as Her Majesty The Queen. Imelda is an astonishing talent and will be a fantastic successor to Claire Foy and Olivia Colman."

After the casting news was announced, Staunton said in a statement, "I have loved watching The Crown from the very start. As an actor it was a joy to see how both Claire Foy and Olivia Colman brought something special and unique to Peter Morgan’s scripts. I am genuinely honoured to be joining such an exceptional creative team and to be taking The Crown to its conclusion."

3. When will the 'The Crown' season 5 premiere?

According to Deadline, the series will not premiere until 2022, due to the Netflix show taking a filming break (although it's not directly related to the pandemic). The exact date has yet to be released, but filming will resume in June of 2021.

4. When will we see 'The Crown' season 5 trailer?

Since the first teaser trailer for season four dropped on Oct. 29—about two weeks before the premiere—fans can expect to see the season five trailer sometime in 2022, just a few weeks ahead of the official release.

5. Is it true that there will be a sixth season?

Though Morgan initially announced that the series would end after five seasons, Netflix confirmed in July that the creator had a change of heart.

Morgan explained, "As we started to discuss the storylines for Series 5, it soon became clear that in order to do justice to the richness and complexity of the story we should go back to the original plan and do six seasons. To be clear, Series 6 will not bring us any closer to present-day—it will simply enable us to cover the same period in greater detail."

Not much is known about the plot, but it's already been confirmed that the cast for season five will return. And as for the time period, season six will possibly be taking place in the early 2000s (so no, we probably won't see Meghan Markle enter the picture).

Still, it looks like royal enthusiasts have quite a lot to look forward to!
