Sadly some of the films from this time are lost. Studios didn’t preserve films in secure temperature controlled warehouses as used today. Documentation and photographs confirm these films once existed. One of the most famous German expressionist films, “Metropolis” (1927 dir. Fritz Lang), had been restored, however in 2005 a reel with more footage was found in New Zealand and in 2008 another reel was found in Buenos Aires, Argentina. The last restoration was in 2010.
