The Last Laugh (aka Der Letze Mann, 1924, dir. F.W. Murnau)

 Metropolis (1927, dir. Fritz Lang)

“This film marks the beginning of an intensive interplay between cinema and architecture. In its most grandiose moments the two fuse to become cinematic architecture, an independent art form.”

-Wolfgang Jacobsen, Metropolis: A Cinematic Laboratory for Modern Architecture
