In the new HBO documentary, “Diana: Our Mother”, Prince William recalls many times where the paparazzi would make his late mother, Diana, cry.

The emotional 65-minute film touches on Princess Diana’s life with her sons Prince William and Prince Harry.

“If you are the Princess of Wales and you’re a mother, I don’t believe being chased by 30 guys on motorbikes who block your path, who spit at you, who shout at you and who react really badly to get a reaction from you, and make a woman cry in public to get the photographs,” William says. “I don’t believe that is appropriate.”

William adds that his mother’s experience with the press has made him be standoffish toward them as an adult.

“I sadly remember most of the time that she… cried about anything… to do with press intrusion,” the Duke of Cambridge recalled.

Both William and Harry started the film to remember Diana, almost 20 years after she was killed in a Paris car accident. This is also the first time both have spoken publicly and openly about their mother and her untimely death.

“Diana: Our Mother” premieres on HBO on July 24.
