In the upcoming documentary Elizabeth At 90 – A Family Tribute, the spare heir reveals his bond with the Queen isn't quite like normal grandparent-grandchild relationships.
"I still view her more as the Queen than my grandmother," Prince Harry shares in the documentary, according to Radio Times. "You have this huge amount of respect for your boss and I always view her as my boss, but occasionally as a grandmother."
In addition to interviewing with six royal family members, filmmaker John Bridcut was granted access to the complete collection of Her Majesty's home movies that were shot through the ages by the monarch and her husband, the Duke of Edinburgh.
This isn't the first time Prince Harry has gone on camera to speak about the Queen. He previously spoke out about how hard it is to follow in her impressive footsteps in the ITV documentary The Queen at Ninety, which aired on Easter Sunday.
"You think to yourself, 'How can I ever fulfill this huge expectation that comes with her and being a member of her family,'" Prince Harry said about feeling the pressure of living up to his grandmother's reputation.
In the meantime, Harry and his older brother Prince William have been planning a grand celebration for the Queen's 90th birthday.
The royal siblings are helping plan the Patron's Lunch, a picnic lunch held on June 12 at London's famed outdoor avenue, the Mall, along the half-mile long road in St. James's Park leading to the gates of Buckingham Palace. The celebrations are already being billed as the Mall's "largest-ever street party," as about 10,000 people are expected to attend. The Patron's Lunch will celebrate the 600 charities and organizations that Queen Elizabeth has supported during her record-breaking reign.
Elizabeth At 90 – A Family Tribute will premiere on BBC One April 21.
