The Crown season 3: First look as Helena Bonham Carter as Princess Margaret

Netflix has unveiled a first look at Helena Bonham Carter as Princess Margaret in The Crown.

The actor replaces Vanessa Kirby, who played the royal in the Golden Globe-winning drama's first two seasons.

"We’re completely terrified," Bonham Carter previously said of taking on the role. "I think also because the first two seasons were such a success, we have the onus of inheriting the responsibility of doing justice to all these genuinely famous people, and then on top of it, inheriting them from this previous generation of actors who’ve done such good jobs.”

Earlier this week, the first image from the third season was released, showcasing Olivia Colman as Queen Elizabeth.

Joining Bonham Carter and Colman for season three are Matt Smith's Prince Philip replacement Tobias Menzies and Jason Watkins, who will appear as British PM Harold Wilson, following on from John Lithgow.

Showrunner Peter Morgan has previously spoken about the recasting, saying that new actors will be brought on every two seasons

“You can’t ask someone to act middle-aged," he said. "Someone has to bring their own fatigue to it. The feelings we all have as 50-year-olds are different than the feelings we all have as 30-year-olds."

The Crown is expected to return to Netflix next year.
