Last week, NEON and Topic Studios released the first official poster for Spencer, the forthcoming drama helmed by Chilean director Pablo Larraín, which will present a snapshot of a critical moment in the dissolution of Diana's marriage to Prince Charles. Stewart appears to be crying into an ornate gown that simultaneously looks fit for a bride and like quicksand consuming the princess. For the film, Vogue Paris reports Chanel recreated a Spring/Summer 1988 Haute Couture show gown — an undertaking that took at least 1,034 hours of work (including 700 just for the intricate embroidery featuring gold and silver sequins forming floral patterns). Princess Diana in Crisis — Breaking Down the Most Telling Shots from the New Spencer Trailer The strapless evening gown, featuring a satin bow tied in front at the waist, is also featured in the film's first teaser trailer, as Stewart's character hurries down a hallway followed closely by two staff members, giving a view of both the front and back of the statement ensemble. The film is set over the course of a weekend in December 1991 when Princess Diana joined the royal family for Christmas as the Sandringham Estate and decided to leave her fractured marriage. "Spencer is a dive inside an emotional imagining of who Diana was at a pivotal turning point in her life," Stewart previously said. "It is a physical assertion of the sum of her parts, which starts with her given name: Spencer. It is a harrowing effort for her to return to herself, as Diana strives to hold onto what the name Spencer means to her." Can't get enough of PEOPLE's Royals coverage?
