Helena Bonham Carter has praised her “extraordinary” family, after learning her grandfather helped thousands of French Jews escape the Holocaust.
Bonham Carter, 53, who is currently starring as Princess Margaret in The Crown, is one of four actors and actresses exploring their grandparents’ wartime stories in a new series for Channel 4, starting next week.
Sir Mark Rylance, Kristin Scott Thomas and Carey Mulligan also appear in their own episodes of My Grandparents’ War, which airs from next Wednesday.
Bonham Carter – who is of Jewish descent on her mother’s side – said she had become “evangelical” about digging into her past since appearing on the show, which commemorates the 80th anniversary of the start of the Second World War.
Her maternal grandfather Eduardo Propper de Callejon was a Spanish diplomat who defied his government’s orders and helped Jews escape the Holocaust during the Nazi invasion of France.
She also learned that her English paternal grandmother Lady Violet Bonham Carter, a mother-of-four and liberal politician, also fought anti-Semitism as a volunteer air raid warden.
Bonham Carter said: “It’s a great family. And I’m proud now to be able to share it.
“Part of me feels like this was just the beginning, because this whole thing was a gift for me.
“We were given a chance to go and explore and ask the questions and hear what really happened, and then have extraordinary surprises.
“The level of research, and the people that did the research, they were extraordinary in what they managed to dig up.
“For me, my family is extraordinary. I was born too late and they died too soon, so for me it was like I met them properly, and had a conversation with them, and I also want to carry on conversing with my mum.
“The conversations that I’ve started, I feel like there’s a lot more.
“I’m almost evangelical in saying that it’s one of the most important things I’ve done.
“I feel like every young person should go and interview their grandparents.”
The programme also sees Bonham Carter interview her grandmother, called Bubbles, at length.
She said: “I did, years ago, interview my mother’s mother for hours.
“All the women in our family never really do stop talking, and I’ve got hours of Bubbles, and she is actually in the documentary, but I do feel it should be part of the national curriculum.
“We should have all our children and grandchildren talk to [our] parents and there should be this handing down.
“What also struck me is that there is all this silence around trauma, so it needs time for people to make sense of it.
“It’s the time for people to speak and for us to find out.”
My Grandparents’ War starts on Channel 4 on Wednesday November 27.
