Patricia Altschul is particular. She does not cook, does not drive and rises at 11 a.m., once her butler has brought breakfast in bed. She gets Botox “everywhere”, only drinks martinis (gin with a twist) and has been married three times (“there could have been more”).

It’s no wonder Altschul—the 84-year-old art advisor, socialite, philanthropist and reality TV star—was an inspiration for the old-money matriarch Victoria Ratliff in HBO’s third series of The White Lotus. Its creator asked the actors who played the Ratliff family to watch Southern Charm, the reality show in which Altschul stars, to prepare their accents and characters.
