Prince Harry has some tough shoes to fill, and he knows it. He's opening up about his reverence for the queen in a new documentary for his grandmother's 90th birthday. Called The Queen at Ninety, royals Prince Charles, Duchess Kate and Prince William share memories in honor of Queen Elizabeth's birthday on April 21.
Harry keeps the queen in mind when he's traveling around the globe, he says. "There is nowhere on this planet that I can think of that she hasn't been in the last 90 years. She's been everywhere," he gushes.
"Sometimes it's quite hard because you go to a place where she hasn't visited for maybe 20 years, maybe 15 years, and you think to yourself, 'How can I ever fulfill this huge expectation that comes with her and being a member of her family?'" (We're sure you don't disappoint, Harry!)
As People reports, the documentary contains Queen Elizabeth's speech, given at age 21, in which she promised to serve her country. Harry, the wild child of the royal family, refers to the speech as "hugely moving."
"It's just incredible to know that someone at that age appreciated and understood exactly what was expected of them, and to basically put duty ahead of everything else so early on in her life is quite remarkable," he says.
The Queen at Ninety airs in the U.K. on Sunday.
