Naomi Watts is set to star in romantic drama “Margot & Rudi,” which tells the true story of ballet legends Margot Fonteyn and Rudolf Nureyev. The film, to be directed by “Mrs. Harris Goes to Paris” filmmaker Anthony Fabian, has been boarded by world sales agency WestEnd Films.

The story unfolds when Fonteyn, the greatest ballerina in the West, is 42 and sensing her career is over. Nureyev is 23, a rebellious Soviet defector — magnetic, explosive, unstoppable. Together, they ignite the stage and become icons of the Swinging Sixties. Fonteyn is reborn by Nureyev’s wild energy, but their bond is complicated by her marriage and his affair with another dancer. To preserve what they have, they will risk everything for one defining ballet—because the only place they can truly be together… is on stage.

Watts, who studied dance before becoming an actress, will star as Fonteyn. She broke through with her performance in “Mulholland Drive” and earned Academy Award nominations for her leading roles in “21 Grams” and “The Impossible.”

She next stars in “The Housewife,” as well as Cody Fern’s untitled debut feature film, with Sarah Paulson, Dianne Wiest and Odessa A’Zion.

On television, she received Emmy, Golden Globe and Critics Choice nominations for her performance in “Feud: Capote vs. The Swans,” and recently starred in “Love Story.”

Alexandr Trush, principal dancer with the Hamburg Ballet, will portray Nureyev. A Russian-speaking Ukrainian ballet star, he has headlined major productions including “Giselle” and “Romeo and Juliet.”

The film also stars Academy Award nominee Richard E. Grant (“Can You Ever Forgive Me?,” “Saltburn,” “Nuremberg”), Academy Award nominee Demián Bichir (“A Better Life,” “Land,” “The Hateful Eight”) and BAFTA nominee Harriet Walter (“Succession,” “The Crown,” “Sense and Sensibility”), with additional cast to be announced.

The screenplay is written by BAFTA nominee Olivia Hetreed (“Girl With a Pearl Earring,” “Mrs. Harris Goes to Paris”).

The creative team includes Academy Award nominee hair and makeup designer Karen Hartley Thomas (“Golda,” The Son,” “The Courier”), choreographer Arthur Pita (“Ex Machina,” “Charlie’s Angels,” “Sunshine on Leith”), and BAFTA-winning costume designer Fotini Dimou (“The Children Act,” “King Lear”), with additional crew to be announced.

The film, which is set to shoot in October, is produced by Mike Goodridge for Good Chaos (“Triangle of Sadness,” “Ballad of a Small Player,” “Quo Vadis, Aida?”), Anthony Fabian for Elysian Films (“Skin,” “Mrs. Harris Goes to Paris”), Olivia Hetreed for Sympathetic Ink and Chris Coen (“Funny Games,” “The Childhood of a Leader,” “Shadow Dancer”). Executive producers are Thom Mount, Jeffrey Berg and Andy Paterson.

Fabian said: “Growing up in Mexico City, watching Margot and Rudi’s performances in the cinema sparked my passion for stories that blend music, theater and dance. The film explores the private joy and pain behind their public personas, capturing their unique chemistry. Ballet sequences from the duo’s most iconic roles and performances together drive the story, using movement and cinematic fantasy to reveal the truth behind a couple as famous in their day as The Beatles. Their love, defying barriers of culture, age, class and sexuality, is romantic, unconventional and thrilling — a love story like no other.”

Fabian’s previous film “Mrs. Harris Goes to Paris” was released worldwide by Focus Features/Universal International Pictures in 2022. It grossed over $30 million at the box office and received BAFTA, Golden Globe and Oscar nominations.

Watts said: “Dance was my first love, and I’ve long dreamed of making a dance film. I feel deeply honored and excited to be playing Margot Fonteyn, one of the greatest dancers of all time. Her relationship with Rudolf Nureyev was extraordinary — both artistically and emotionally — and I’m thrilled to be exploring it with such sensitivity and imagination under the direction of Anthony Fabian.”

Maya Amsellem, managing director of WestEnd Films, said: “’Margot & Rudi’ is a sweeping and beautiful story about two iconic artists who redefine each other at a pivotal moment in their lives. Naomi Watts is set to deliver one of the most transformative performances of her career, combining emotional intensity with the physicality of dance. With Anthony Fabian’s visionary direction and the film’s bold, cinematic use of ballet, this will be a powerful big-screen experience we’re excited to bring to the international market.”

WestEnd will introduce the film to buyers at Cannes Film Festival.
