Britain's Prince Harry is collaborating with Oprah Winfrey on a new television series tackling the issue of mental health. The multi-part documentary series, which will air on the Apple TV platform in 2020, was co-created and produced by the Duke of Sussex and Winfrey. It aims to inspire viewers to have an "honest conversation about the challenges each of us faces," according to a statement from Kensington Palace. The statement added that the project will attempt to equip people "with the tools to not simply survive, but to thrive." Harry said he was "incredibly proud" to be working alongside Oprah on the "vital" series. "I truly believe that good mental health -- mental fitness -- is the key to powerful leadership, productive communities and a purpose-driven self," Harry said.
