Prince William, Prince Harry, and Kate Middleton launched a film series

The ever-enterprising block of young British royals,Prince William,Kate Middleton, and Prince Harry, have launched a 10-part video series called "O.K. to Say" to accompany Heads Together, "a new campaign to end the stigma around mental health," according to the online literature. The initiative was launched in early 2016, and the videos were released Thursday. Each one shows conversations about conversations that were between a person suffering from mental illness and a loved one. They touch on everything from grief to depression to substance abuse.

"Attitudes to mental health are at a tipping point," reads the accompanying statement, which is attributed to the Duke and Duchess of Cambridge and Prince Harry. "We hope these films show people how simple conversations can change the direction of an entire life. Please share them with your friends and families and join us in a national conversation on mental health in the weeks ahead."

Prince Harry was on hand the day at least one of them was filmed. He's shown talking to one of the participants, Rio Ferdinand, a British soccer player who recently lost his wife to breast cancer.

Most of Kate Middleton's and many of Prince William's public engagements in the U.K. center on mental health initiatives, from World Mental Health Day receptions to speaking on behalf of their organization at London's Institute of Contemporary Art. The Duchess recently completed a solo tour of the Netherlands, too, where she discussed much of the same at the British ambassador's residence there.
