The backdrop to the trailer included a photograph of the four eldest grandchildren: Peter and Zara Phillips, and Princes William and Harry, along with the Queen and Prince Philip.
In the trailer, Prince William could be heard saying: “He’s always been a huge presence behind everything we’ve done really.”
Prince Harry follows with: “What you see is what you got with my grandfather. He was unapologetically him.”
Their cousin Zara Tindall looked emotional as she said: “You never really prepare yourself for losing him because he was always there.”

Prince Charles looked the most emotional as he concluded the trailer with: “We were lucky to have him for nearly 100 years!”
The programme, which will be titled: ‘Prince Philip: The Royal Family Remembers’ will air on BBC One on September 22, 2021, where many of the major Royal Family members are expected to take part.
All of the Queen and Philip’s children are expected to take part, as well as their adult grandchildren.
A body language expert spoke to Express.co.uk about the four Royal Family members who appeared in the trailer honouring Prince Philip and explained the four different stages of grief that were shown.
Judi said: “We are shown four very different states of grief here.
“Harry sits in the most animated pose, legs splayed and hands gesticulating as he looks keen to link with his grandfather via postural echo.
“He picks out a description that could also apply to himself: ‘What you see is what you get’.
“This, like his previous comments about his banter, look and sound like an attempt to show bonds via similarity.
The tribute is a must-see event for royal fans because as well as their access to senior members of the Royal Family, the filmmakers were also allowed to meet Philip’s loyal staff and capture his private office, library, and study.
The BBC originally conceived of the programme as part of the Duke of Edinburgh’s 100th birthday celebrations.
However, it was altered after his death in April, and now features interviews with his family recorded before and after his passing.
There are poignant recollections, plenty of humour and numerous fresh insights into the character and legacy of the royal patriarch.
The film is described as a portrait of a man with a unique place in royal history and told by the people who knew him best.
