Metropolis was a German silent film released in 1927 and directed by Fritz Lang. An expressionist, science-fiction piece, it is set in a futuristic dystopia and explores the relationship between workers and and capitalists.

The film was cut heavily after initial screenings. Various versions have been unearthed in the decades since. In 2008, a version 30 minutes longer than any previously known cut was discovered in Argentina. It was restored and screened in February 2010.
