The first completed version of the film lasted three and a half hours, and the premiere version in Berlin, Germany, lasted 153 minutes, and was edited by the publisher into a two-hour version. Released in Germany and overseas. However, based on factors such as box office revenue and political censorship, the versions that have been shown around the world in the past have deleted more than half of the content and edited versions of varying lengths. Since the Second World War, the original master of the film has been scattered all over the world and it is difficult to find it. Although it has been re-screened many times in the past, it is not the original complete version. In 2001, a restored version led by the Munau Foundation was launched at the Berlin Film Festival. After years of excavation and verification, about a quarter of the fragments are considered to be lost forever. In the same year, it was listed as a world documentary heritage by UNESCO.
In 2008, in the Film Museum in Buenos Aires, Argentina, a 16-centimeter copy of the film was found, and about 23 minutes of missing footage was found. The film has been restored with the latest digital technology, combined with a 147-minuterestoration version of the original soundtrack performed live , and will be re-released at the 2010 Berlin Film Festival. This version will be released on Blu-ray Disc.
