Olivia Wilde is talking about the O-word. No, not the Oscars, but her approach to sex scenes in her new movie, “Don’t Worry Darling.” “Men don’t come in this film,” she declares over cucumber sandwiches and scones at Claridge’s, just blocks away from Buckingham Palace. “Only women here!” In Wilde’s second directorial outing after 2019’s indie high school coming-of-age story “Booksmart,” Florence Pugh and Harry Styles star as a married couple living in a quaint, experimental utopia called Victory. Pugh plays Alice, a “Mad Men”-type housewife whose reality begins to crack, revealing disturbing truths underneath her seemingly perfect world. When the trailer for the sci-fi thriller dropped in May, social media was buzzing about Styles’ character, Jack, going down on Alice on top of a dining room table.
