The film underwent a 4K restoration in 2022 by original production company Societé Cinématographique Lyre in association with Titanus with the support of the French CNC and the Italian Ministry of Culture to celebrate the 100th birthday of director Gianfranco De Bosio. The restoration was based on all the negative elements available in Italy and France, was undertaken by the Video Master Digital lab in Rome and the Hiventy lab near Paris, and ended up being dedicated to de Bosio, who died that same year.
