Oprah Winfrey and Prince Harry will be “partners, co-creators and executive producers” on an upcoming multipart docuseries for Apple that will tackle mental health issues.

“I truly believe that good mental health — mental fitness — is the key to powerful leadership, productive communities and a purpose-driven self,” Harry said in a Wednesday announcement on Instagram.

According to the statement, the British royal and the media magnate have been developing the new series, which will focus on mental illness and mental wellness, for months. The series will “[inspire] viewers to have an honest conversation about the challenges each of us faces, and how to equip ourselves with the tools to not simply survive, but to thrive.”

In April 2017,  Harry spoke to The Washington Post about how losing his mother, Princess Diana, in 1997 when he was 12 created a great deal of grief that he had to learn how to navigate. Since then, he has become an advocate for mental wellness and has shared his story with the public to help eliminate the stigma surrounding mental illness.  

“It is a huge responsibility to get this right as we bring you the facts, the science and the awareness of a subject that is so relevant during these times,” the prince also said in his statement.  “Our hope is that this series will be positive, enlightening and inclusive — sharing global stories of unparalleled human spirit fighting back from the darkest places, and the opportunity for us to understand ourselves and those around us better. I am incredibly proud to be working alongside Oprah on this vital series."

Winfrey commented, “Delighted to be partnering with you. Hope we shed a lot of light. And change some lives!”

The docuseries is slated to release in 2020.
