Prince Harry and Oprah Winfrey released a new trailer for their upcoming mental health series “The Me You Can’t See,” which is set to premiere on Apple TV+ on May 21. In the trailer, Harry and Oprah can each be seen getting emotional, giving an idea of the tone of the show.

“All over the world people are in some kind of mental, psychological, emotional pain,” Oprah told Harry in the trailer. “Being able to say, ‘This is what happened what happened to me,’ is crucial.”

“To make that decision to receive help is not a sign of weakness,” Harry said. “In today’s world, more than ever, it is a sign of strength.”

A 12 year-old Harry was seen looking on as his mother’s casket passed by and a voiceover said, “Treating people with dignity is the first act.” Harry lost his mother Princess Diana back in 1997, when she was killed in a car crash in Paris, France while being chased by the paparazzi.

Meghan Markle even makes a cameo, smiling and looking over Harry’s shoulder as he worked on his laptop.

“The results of this year will be felt for decades,” Harry added as a photo of Meghan reading to their son Archie is shown. “By kids, families, husbands, wives – everybody.”

The trailer also revealed some of the series’ interviewees, including Glenn Close and Lady Gaga.

“I don’t tell this story for my own self-service. I’ve been through it and people need help,” said Gaga, who is identified by her birth name of Stefani in the clip.

Harry previously expressed hopes that it will show that “there is power in vulnerability.”

“We are born into different lives, brought up in different environments, and as a result are exposed to different experiences,” he said. “But our shared experience is that we are all human. The majority of us carry some form of unresolved trauma, loss, or grief, which feels – and is – very personal.”

“Yet the last year has shown us that we are all in this together and my hope is that this series will show there is power in vulnerability, connection in empathy and strength in honesty,” Harry continued.
