The recently released film about Finnish singer Kaija Koo has garnered attention and controversy primarily due to the performance of lead actress Oona Airola, who sings Kaija Koo's songs in the movie. In a short documentary detailing the making of the film, director Selma Vilhunen revealed that Airola performs all the songs herself. However, during the sound editing stage, elements of Kaija Koo's own sound were mixed into the tracks. This revelation has raised questions about authenticity and the artistic choices made in the production of the film.

The discussion around the music intensified when Kaija Koo herself disclosed in an interview with Yle that artificial intelligence was utilized in some of the singing scenes. She mentioned that her voice was slightly amplified in the mix for the sake of sound, which stirred a debate on the modern technology's role in music and film production. The intersection of AI and artistry has become a focal point, reflecting broader trends in the entertainment industry regarding the blending of human talent and technological enhancement.

Amid these discussions, producer Jukka Immonen, played by actor Aku Sipola, also commented on the evolving media narrative surrounding Airola's performance. He highlighted the focus shifting to the quality of Airola's rendition of the songs. This ongoing dialogue not only emphasizes the unique challenges faced in adapting real-life figures for film but also reveals the complexities artists encounter today as they navigate the integration of technology into their creative expressions.
