For decades, Fritz Lang’s expressionist sci-fi Metropolis has been considered an indisputable classic. This fact has not changed. The film, however, has. With its running time having been cut by a quarter shortly after its German premiere in 1927, the full version of Lang’s epic was long presumed lost, until it miraculously turned up in Argentina two years ago. Having been recut and restored, the version we see now is the closest audiences have been to Lang’s vision in over 80 years – and it’s just as astonishing as you might expect.
