Following its world premiere in 1927, half an hour was cut from Fritz Lang's masterpiece and lost to the world.
Eighty years later a spectacular discovery was made when the footage was found in a small, dusty museum in Buenos Aires.
The film was then painstakingly reconstructed and digitally restored with a new recording of the original score.
At last audiences could see the iconic futuristic fairy tale as Lang had envisioned it.
Simply magnificent.
