Stefania Sandrelli's voice was dubbed by Adriana Asti.

The film was restored in 2008 and shown as part of the retrospective "Questi Fantasmi: Cinema Italiano Ritrovato" at the 65th Venice International Film Festival.

Stefania Sandrelli was only 17 at the time of filming.

The film is based on an incomplete novel of the same title by Alberto Arbasino. The first version of the novel was published as a story in Il Mondo (The World) magazine in 1960. The final version was not published until 1972.
