Claire Foy and Matt Smith graced the red carpet premiere of "The Crown" season 2 at Leicester Square in London on Tuesday, Nov. 21. The two reprised their roles as Queen Elizabeth II and Prince Philip, respectively, but this will be the last time that fans are going to see them portray these characters. In "The Crown" season 3, they are going to be replaced with new cast members to play an older version of their roles.

So far, the only known new cast member joining the Netflix series' third installment is Olivia Colman. The 43-year-old star will portray the United Kingdom's Queen during her reign in the 1970s.

In an interview with Metro News, Foy expressed her excitement to see Colman in "The Crown" season 3 take over her role. "I just think it's hers. I can't wait to see what she does with it," she said. And although she started to play the character of Queen Elizabeth for the show's two seasons, she insisted that she never owned it. 

Meanwhile, talking about the upcoming "The Crown" season 2, Smith told the reporters that they had a wonderful time filming the show. "We're into the '60s and there are some interesting storylines," he said.

The 35-year-old actor also teased that fans may think they already know the new installment's story, but they actually have no idea what is going to happen. He then explained the second season is a "difficult watch" because of the complicated stories the royal family has.

Aside from the 60s, the story will show Princess Margaret (Vanessa Kirby) riding a motorbike, and feature difficulties in her marriage. Also, fans will have a glimpse of the young Prince Philip (Smith) in "The Crown" season 2 and a backstory of his younger years.

"The Crown" season 2 is set to be released on Friday, Dec. 8, on Netflix.
