Hathaway glided across the carpet in a Lever Couture gown, crafted from shimmering mesh ribbons. This sleeveless piece featured high shoulder straps and a side slit. The outfit was completed with silver Christian Louboutin heels and Bulgari jewelry adorned with 18-karat white gold. She wore diamond and emerald earrings and rings from the brand's iconic Serpenti line, together worth over $100,000. The "Mother Mary" star was assisted by her longtime stylist Erin Walsh, whose clients also include Selena Gomez and Alison Brie. The film, directed by David Lowery, is described as a "psychosexual pop opera" blending elements of drama, music, and psychological thriller. The plot follows a famous singer who reconnects with a estranged friend and former stylist, played by Michaela Coel, ahead of her major tour. The trailer begins introspectively, with narration by Coel, but gradually shifts to a darker and more unsettling tone, hinting at elements of horror and psychological tension. Particular attention is drawn to the film's music, with Hathaway performing the original song "My Mouth Is Lonely for You" in the trailer, co-written by FKA twigs alongside multiple producers.
