The raw cut of this film from 1973 was banned in East Germany and the film material subsequently destroyed. By coincidence, a working copy survived and was rediscovered by cinematographer
Roland Gräf in 1989/90. When the original color copy proved unplayable, he had a black and white version produced which finally premiered in cinema in October 1990. Afterward, the film disappeared again until 2009, when it was found and reconstructed for a wider 2010 release - 37 years after it was made and originally scheduled for premiere.
