I’ve learned that Vanessa Kirby (Jupiter Ascending) is in negotiations to play Princess Margaret in The Crown, Peter Morgan’s decades-spanning drama series that explores the inside story of Queen Elizabeth II and Britain’s post-war Prime Ministers. The 10-episode first season is slated to premiere on Netflix in 2016.

Inspired by Morgan’s hit award-winning West End Play The Audience, each season of The Crown will explore the political rivalries and personal intrigues across a decade of Queen Elizabeth II’s reign, exploring the delicate balance between her private world and public life. As we previously reported. Claire Foy has been in negotiations to play the young Queen.

Season one begins with a 25-year-old Princess faced with the daunting prospect of leading the most famous monarchy in the world while forging a relationship with the domineering, war-hardened Prime Minister Winston Churchill. Netflix would not comment on Kirby’s casting, first reported by DailyMail.

Kirby recently wrapped BBC drama The Dresser opposite Anthony Hopkins and Ian McKellen. Her other credits include BBC’s Great Expectations and features About Time and Insomniacs.

The Crown is produced by Sony-owned British production company Left Bank Pictures in association with Sony Pictures TV. Morgan, Daldry and Harries will serve as executive producers along with Robert Fox and Matthew Byam Shaw.
