It was earlier reported that Joan Collins is set to star as Wallis Simpson in a biopic on the American socialite, whom King Edward VIII married after renouncing the throne. In the latest development, Isabella Rossellini has been tapped to play layer-writer-Simpson's confidante Suzanne Blum in the film, with the working title The Bitter End.

Reportedly, the film from director Mike Newell and writer Louise Fennell charts the last few years in Simpson's life. Rossellini stated that she is "thrilled" to be part of the Wallis Simpson biopic. She added, "Louise Fennell’s script allows us to delve into the complex and devastating relationship between these two iconic women, the profound impact they had on one another and their lasting mark on history."

Rossellini recently earned her first Academy Award nomination for her performance in Conclave, the thriller set in the Vatican. She is nominated in the Best Supporting Actress Oscar category, alongside Monica Barbaro (A Complete Unknown), Ariana Grande (Wicked), Felicity Jones (The Brutalist), and Zoë Saldaña (Emilia Perez).
