Prince Harry and Meghan Markle’s return to Britain has raised plenty of questions, from their children’s schooling to Harry’s relationship with his family. But a new claim suggests there could be another, far more personal reason behind Harry’s decision to spend more time in the UK. Just days after returning, Harry was reportedly seen at Tower Bridge Studios in London, where he spent much of the day working on a confidential project. The production company involved has not revealed what was being filmed, leaving the nature of the project unknown. That mystery has gained attention because royal commentator Richard Kay has claimed that Harry may be developing a television film about his late mother, Princess Diana. According to Kay, Harry has allegedly been contacting people who knew Diana and asking them to contribute, with the project potentially occupying much of his time over the next year.

The timing has made the claim especially intriguing. August 2027 will mark 30 years since Diana’s death, creating renewed interest in her life and legacy. Harry was only 12 when he lost his mother, and he has spoken openly over the years about how deeply the experience affected him. Before returning to Britain, he also reportedly visited Althorp Estate, where Diana grew up and was laid to rest, with a film crew said to have been present. However, neither Harry nor Meghan has officially confirmed that a Diana film is being produced, and there is no proof that his studio visit was connected to the alleged project. If the claim does prove accurate, the production could become one of Harry’s most personal projects yet. It could also bring renewed attention to his relationship with Prince William, since Diana was equally their mother and her legacy remains deeply connected to both brothers.
