Maritta Viitamäki, an actress who became a sex symbol through her role in the controversial film 'Maa on syntinen laulu', shared her experience of having to seek parental consent for her daring role due to her being underage at the time of filming. The film, which premiered in 1973, is based on Timo K. Muka's novel and explores the sexual awakening of a young girl named Marta in 1940s Lapland, leading to her romantic interest in a reindeer herder named Oula, whom her father Juhani disapproves of due to Oula's notorious reputation.

Viitamäki described how she was discovered for the role in the woods, an unorthodox casting move that highlights the film's distinctive and bold approach. The film's narrative touches on themes of youthful desire and societal constraints, especially considering the cultural context of 1960s and 70s Finland, where growing sexual liberation was still often met with resistance. During that period, the legal age of majority in Finland was gradually lowered, reflecting changing social norms regarding adulthood and responsibility.

Despite being underage, Viitamäki's decision to take on the role without parental consent demonstrates her determination and ambition as an artist, even when faced with significant challenges. The film remains a significant piece of Finnish cinematic history, not just for its narrative but also for its cultural commentary on the dynamics of love, reputation, and youthful rebellion in a conservative setting.
