Who Played Princess Diana in The Crown Season 4?

Emma Corrin was announced as Princess Diana in July 2019, a casting decision that generated enormous anticipation. Corrin was relatively unknown to mainstream audiences at the time, having appeared primarily in theatre and small TV roles. The Telegraph described Corrin’s performance as a standout, following Diana from her early connection with Charles through courtship, Balmoral, marriage, loneliness, bulimia, and her emergence as a more confident public figure as the marriage unravels.

How was Emma Corrin cast and what preparation did she undertake?

The casting process was kept under wraps until the official announcement. Once cast, Corrin worked with a dialect coach to master Diana’s distinctive voice and mannerisms. She also studied hours of archival footage to capture the princess’s physicality, from the famous shy tilt of the head to her evolving posture as she grew in confidence. Corrin wore authentic replicas of Diana’s clothing, which helped her embody the character more fully.

What did critics say about Emma Corrin’s performance?

Critical reception was overwhelmingly positive. The Guardian called Corrin “a revelation as Diana,” noting that she captured both vulnerability and strength. The performance earned Corrin a Primetime Emmy nomination for Outstanding Lead Actress in a Drama Series. Some debate emerged among viewers about whether the voice was an exact match, but most reviewers praised the emotional depth she brought to the role.

Who Played Margaret Thatcher in The Crown Season 4?

Gillian Anderson was confirmed as Margaret Thatcher in November 2019. The casting was notable because Anderson, an American-born actor, was taking on one of the most recognisable British political figures of the 20th century. Promotional interviews for the season specifically paired her performance with Corrin’s as two transformative additions to the cast.

Was Gillian Anderson’s portrayal of Thatcher considered accurate?

Anderson’s portrayal received widespread acclaim. Variety described it as “chillingly accurate – from the voice to the posture.” To achieve the likeness, Anderson underwent three hours of makeup daily, including prosthetic pieces that reshaped her nose and jawline. She also worked intensively on Thatcher’s distinctive speaking patterns and physical rigidity.

How did Gillian Anderson prepare for the role?

Preparation involved studying Thatcher’s speeches, cabinet meetings, and interviews. Anderson has said in interviews that she wanted to capture not just the public persona but also the private moments of doubt and resolve. The role earned her an Emmy nomination for Outstanding Supporting Actress in a Drama Series.

Which Guest Stars Appeared in The Crown Season 4?

Beyond the headline names, season 4 included several supporting actors who portrayed members of the Thatcher family, royal staff, and other historical figures. The Telegraph cast article explicitly identifies several of these roles.
