Her life story certainly reads like a movie script. Lady Elizabeth Anson, who died this past November at 79, was a cousin to Queen Elizabeth II and the doyenne of party planning who threw her first blue-blooded bash at the age of 19. She claimed to have invented the industry (take that, Carole Middleton). Indeed, her over five-decade career included throwing birthday parties for both Prince William (his 18th) and Margaret Thatcher (her 80th). Along the way, the aristocrat lost, she once claimed, nearly everything during the near collapse of Lloyd’s of London in the 1990s, a hoard of jewelry when robbers broke into her home and attacked her while she was watching TV, and a years-long lawsuit against Ivana Trump. Dubbed “the Battle of the Bouffants,” it involved a tussle over Anson’s claim that Trump had invited twice the agreed guest list for a party that included hot-air ballooning. Trump fired back that the bill was “ridiculous” for such a small get-together. The judge ruled in Trump’s favor.

So it’s fitting that Lady Elizabeth’s life is about to become a movie—though not one you can catch at a multiplex (whenever those reopen) or stream on Netflix. Rather, director Andrew Gemmell’s firm has been hired by her kin to make a bespoke biopic that chronicles her life and times for posterity—less a family album than a family film.
