What is Prince Philip: The Royal Family Remembers about?

The hour-long trip down memory lane will show never-before-seen footage from Queen Elizabeth’s cine-film collection.

More than a dozen members of the British royal family will take part, though the Queen was not mentioned in the official announcement of the show.

Due to the documentary first being commissioned to mark the Duke’s 100th birthday, it will also feature interviews conducted before his death.

The documentary-makers have been inside Buckingham Palace to meet the Duke’s long-serving staff and to capture his study, private office and library, exactly as they were during his seven decades at the heart of royal life.

The official synopsis of the documentary describes it as “an unrivalled portrait of a man with a unique place in royal history - by those who knew him best.”

Which royal family members will take part?

While Oxford Films, the production company making the documentary, has not been forthcoming with names, it has been confirmed that Prince Philip’s children and grandchildren will all take part.

In the documentary, Prince Charles reveals his last conversation with his dad, recalling that he phoned him on 8 April to discuss arrangements for the Duke’s 100th birthday.

In the final conversation, Charles said:“We’re talking about your birthday.”

He then repeated it a little louder since the duke was hard of hearing: “We’re talking about your birthday! And whether there’s going to be reception.”

“Well, I’ve got to be alive for it, haven’t I?” Philip replied, to which Charles responded: “I knew you’d say that.”

“We were lucky to have him for nearly 100 years,” said Prince Charles in the interview.

Prince William and Harry have also shared memories of their grandfather, and revealed what a important role he played in their upbringing.

William recalled driving through the Balmoral Estate with Philip, when they drove passed some young hikers taking part in The Duke of Edinburgh award, a scheme Prince Philip founded.

He wound down his window and asked “how are you getting on” to the youngsters, to which the smallest replied “jog on, grandpa.”

According to William, the duke found the exchange hilarious and joked to William “the youth of today.”

Prince Harry described his grandfather as “unapologetically him.”

In his first interview as a joint project with the rest of the royals since stepping down from his royal duties, he said: “What you see is what you got with my grandfather. He was unapologetically him.”

Speaking from his California home, he added: “From my grandmother’s perspective, to have someone like that on your shoulder for 73 years of marriage – it doesn’t get better than that.”

Zara Tindall, child of Princess Anne, also commented on the wave of grief she felt when the Duke passed away.

“He was getting older and he absolutely hated it,” she said, “He was the worst patient in the world. But, actually, you never really prepare yourself for losing him because he was always there.”

Camilla, Duchess of Cornwall, also commented on her father-in-law’s legacy, stating: “’It felt like the end of an era. They’re a very difficult generation to live up to but I’m very proud and very pleased that I knew him.”

Prince Andrew also took part in the documentary, though it is not known when his interview was conducted.

The prince has been recently photographed visiting his 95-year-old mother at her Balmoral home in Aberdeenshire, as a lawsuit was filed against him in New York relating to sexual assault.
