Helena Bonham Carter to play Princess Margaret in The Crown

Helena Bonham Carter has been tapped to play Princess Margaret, in Season 3 of Netflix's The Crown, reports news.com.au.

Netflix recently announced that Olivia Colman would be replacing Claire Foy as the Queen in Seasons 3 and 4 of the show.

Bonham Carter will reportedly take on the role of Princess Margaret, the Queen's late sister, in the upcoming series, Variety reports.

Vanessa Kirby has played the younger Margaret in the last two seasons.

Series creator Peter Morgan has previously said he intended to replace key cast members in later seasons of The Crown to better portray the main characters as they age.

A key piece of the casting puzzle still to be confirmed is who will replace Matt Smith as Prince Philip, the Queen's husband, in the Netflix series.
