The film is based on the successful stage play of the same name by , which premiered at the Tampere Theatre Festival in 1984. According to Oranen, her inspiration came from a tabloid headline concerning Minister Matti Ahde, which later turned out to be completely unfounded.

Oranen was dissatisfied with the final result and publicly distanced herself from the film.
