A planned film about Queen Elizabeth II's friendship with trusted aide Angela Kelly has revived scrutiny of Prince Harry and Meghan Markle's disputed wedding-tiara arrangements, with one royal commentator suggesting Harry should be "quaking in his boots" over what the production might reveal.

The project, reportedly titled Trouble, is a scripted drama for Fox Searchlight, rather than the documentary described in earlier coverage. Jeremy Brock is writing the screenplay, with Thea Sharrock attached to direct, according to information supported by Brock's agency.

Neither the film's final content nor its release date has been announced. There is no confirmation that the disagreement known as "Tiaragate" will appear, that Kelly has contributed to the production or that Harry has expressed concern about it.

The speculation stems partly from remarks by The Daily Mail's Charlotte Griffiths, who suggested the story could extend beyond the already public dispute. She referred to an unspecified incident involving the Sussexes around the same period, without providing details that would establish what happened.

"Apparently, there's another incident from around that time that they, Harry and Meghan, are praying does not come out in this drama," Griffiths said. Her subsequent "quaking in his boots" remark expressed her assessment, rather than a documented response from Harry.

The tiara disagreement concerned access to Queen Mary's Diamond Bandeau before the couple's May 2018 wedding. According to Finding Freedom, the 2020 biography by Omid Scobie and Carolyn Durand, Harry became frustrated with arrangements for Meghan to use the tiara during a hair trial.

That account describes a dispute over scheduling and access to an already selected piece of jewelry. It differs from versions suggesting Kelly simply prevented Meghan from choosing a wedding tiara.

Harry later criticized Kelly in his memoir Spare, describing her as "obstructive" and a "troublemaker." Reporting based on Robert Hardman's 2026 book has offered a competing account, including claims that Elizabeth supported Kelly's handling of the arrangements.

The disagreement could provide material for a drama, but the filmmakers have not said whose account, if any, they intend to portray. Brock previously wrote A Very Royal Scandal, the 2024 television series dramatizing Prince Andrew's 2019 Newsnight interview with Emily Maitlis.

Discussing the project on Palace Confidential, The Daily Mail's Richard Eden said Elizabeth regarded Kelly as being "like a sister." He also described "really lively rows" involving Kelly and the Sussexes and characterized Harry's treatment of her in his memoir as "particularly unpleasant."

Kelly's responsibilities included serving as personal assistant, adviser and curator, alongside her work dressing the monarch. She left royal service after Elizabeth's death in 2022 and subsequently moved from her home on the Windsor Estate.

In an interview with Vanity Fair, Kelly described the foundation of their friendship: "We both knew we had trust, loyalty, and understanding. The Queen was my best friend and I miss her every day."

She also recalled listening to BBC Radio 2 together and dancing when ABBA's "Dancing Queen" played. Elizabeth would sing and sway, Kelly said, sometimes telling her more enthusiastic companion to "move over."
