Prince William has declined to participate in any television documentary marking the 30th anniversary of Princess Diana's death, despite receiving multiple offers and meeting with BBC leadership. The heir to the throne's decision is motivated by a desire to avoid putting himself and his estranged brother Prince Harry "pitted against each other" in a film, and reflects that the matter remains "really emotional" for him despite tributes made nine years earlier.

William was 15 when Diana died in a car crash in Paris in August 1997. The brothers last appeared together on screen for a 2017 ITV documentary on the 20th anniversary of her death, but have not spoken since Queen Elizabeth II's funeral in September 2022. Meanwhile, Prince Harry is understood to be exploring his own commemorative projects through his Archewell Productions and has approached Diana's friends and relations, including her brother Earl Spencer, to take part in a potential film honouring her legacy.
