Prince Harry said he wanted to interview controversial figures like Vladimir Putin, Donald Trump, and Mark Zuckerberg for a podcast on childhood trauma, according to Bloomberg.

The podcast, which he pitched to multiple producers in the United States, would feature extended interviews with contentious guests, investigating the ways in which their adulthoods were impacted by their experiences as a child.

Prince Harry’s production team members said they were concerned that securing interviews with such guests would be impractical, and they worried that the people Prince Harry wanted to speak with might not share much about their childhood or personal lives.

Prince Harry considered hosting podcasts on fatherhood and major societal topics, like climate change and religion. For the episode about religion, according to sources who spoke to Bloomberg, Prince Harry wanted to speak to Pope Francis.

A partnership between Spotify and Archewell Audio, the podcast company that Prince Harry and his wife Meghan Markle founded, was announced in December 2020. However, the partnership has only yielded one season of “Archetypes,” a podcast hosted by Markle. Prince Harry’s podcast ideas have not yet made it to production.

Prince Harry and Markle signed a deal, estimated to be worth around £15.5 million ($20 million), to produce podcasts shortly after their departure from the royal family.

In a recent podcast with Bill Simmons, a Spotify executive, and popular podcaster, Simmons teased a recent podcast by the couple.

“I wish I had been involved in the ‘Meghan and Harry leave Spotify’ negotiation. ‘The F**king Grifters.’ That’s the podcast we should have launched with them,” he said. Simmons also said he spoke with Prince Harry “to try and help him with a podcast idea.”
