Prince Harry and Oprah Winfrey star in trailer for mental health docuseries The Me You Can't See

In addition to their behind-the-camera roles, both Oprah and Harry will feature in the docuseries themselves, while other familiar faces include Lady Gaga and Glenn Close.

The series has partnered with 14 accredited mental health professionals and organisations, with the intention of informing people about different ways of finding treatment and overcoming their issues.

"To make that decision to receive help is not a sign of weakness," says Prince Harry. "In today's world, more than ever, it is a sign of strength."

Check out the first trailer below, which introduces the key subjects of the series.

The Me You Can't See is directed by Dawn Porter (John Lewis: Good Trouble) and Asif Kapadia, who won an Academy Award and a BAFTA among other honours for his 2015 documentary about the life of Amy Winehouse.

Every episode of the series will be released at once on Friday 21st May, exclusively on Apple TV+, which is available for a subscription cost of £4.99 per month.

Since stepping away from the rest of the Royal Family, Prince Harry has made moves into the entertainment industry by signing a multi-year deal to make content for Netflix.

He has also forged a close relationship with American superstar Oprah Winfrey, who interviewed Prince Harry and Meghan Markle back in March for a television special that made headlines around the world.

The Me You Can't See launches on Apple TV+ on Friday 21st May. While you're waiting, check out more of our Documentaries coverage or visit our TV Guide to see what's on tonight.
