Production

Development

The film was announced in March 2024. Director Michał Kwieciński had previously worked with Eryk Kulm on his 2022 film, Filip. When Kulm expressed that Frédéric Chopin was his dream role, Kwieciński began researching the composer. He was inspired by Joachim Trier's 2021 film The Worst Person in the World in deciding to present Chopin's life in distinct vignettes.
With a budget of PLN 72 million, it is one of the most expensive productions in Polish history.

Casting

Eryk Kulm joined the cast in June 2024. To prepare for the role, he read two extensive biographies about Chopin. He also spent three months learning piano pieces by Chopin to play in the film. Pianist Janusz Olejniczak oversaw Kulm's musical preparations. Lambert Wilson was announced as a cast member on 29 August 2024.

Filming

The film was shot over four months, and required the work of 260 actors, 5,000 extras, and 600 crew members. Principal photography began in Poland in August 2024.
