Fritz Lang’s film Metropolis had its premiere in 1927. Production took 17 months, with 310 days and 60 nights of shooting, and used 620,000 meters of negative film. The set designer Otto Hunte said that one traffic effect alone took almost six weeks of minutiös genaue Arbeit, meticulously exact work. The budget was planned at 1.5 million Reichsmarks. The film cost about four times as much. The management of the studio, Ufa, felt blackmailed by Lang’s constant demands for more money.
