Helena Bonham Carter has been tapped to play the Queen’s sister, Princess Margaret, in Season 3 of Netflix’s “The Crown.”

Netflix recently announced that Olivia Colman would be replacing Claire Foy as Queen Elizabeth II in Seasons 3 and 4 of the show, a role that Bonham Carter had herself been linked to. Vanessa Kirby (“Everest”) played Margaret, who is considered one of the more controversial Royals, during the past two seasons of the drama.

Series creator Peter Morgan has previously said he intended to replace key cast members in later seasons of the Left Bank-produced series to better portray the main characters as they age.

Seasons 3 and 4 have not been officially ordered, but early production is said to be underway.

Bonham Carter can be seen next in “Ocean’s 8.” She is repped by WME and Conway van Gelder Grant. She has not yet signed on to play Princess Margaret, Elizabeth’s only sibling and at one point second in line to the throne, but is close to doing so. Netflix and Bonham Carter’s reps declined to comment.

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.
