The goal of digital restoration was to make the available in a form similar to how it could have been seen and heard by an audience at the time when it was first released in 1964. As a result, various features that originate from a shooting of the film or its laboratory processing have been preserved and are evidence of the technologies and creative approaches of the time.
The source of the digitization were film materials preserved in Národní filmový archiv, Prague. The image was digitized from the original negative, the missing parts were taken from a duplicate positive. The source of the sound was a duplicate positive.
The restoration was done by the Cinepost Barrandov studio in Prague, under the supervision of Národní filmový archiv, Prague, in 2017.
