The work of Fritz Lang inspired which Madonna video?

"Express Yourself" is a song by American singer-songwriter Madonna, from her fourth studio album "Like a Prayer" (1989). It was released as the second single from the album on May 9, 1989 by Sire Records. The song was included on the greatest hits compilation albums "The Immaculate Collection" (1990), and "Celebration" (2009). "Express Yourself" was the first song that Madonna and producer Stephen Bray collaborated on for "Like a Prayer". Written and produced by them, the song was a tribute to American funk and soul band Sly and the Family Stone. The main inspiration behind the song is female empowerment, urging women never to go for second-best and to always express their inner feelings.

The music video was directed by David Fincher and filmed in April 1989, at Culver Studios in Culver City, California. It was produced by Gregg Fienberg, under Propaganda Films, with editing by Scott Chestnut, principal photography by Mark Plummer, and Vance Lorenzini as the production designer. "Express Yourself" music video was inspired by the Fritz Lang classic film "Metropolis" (1927), and featured an epigraph at the end of the video from the film: "Without the Heart, there can be no understanding between the hand and the mind".
