It's fortune telling and chaos as death that riddles Wiene's fantastical landscape. At the time, Caligari was said to have unsettled its audiences. Critics applauded its ability to "squeeze and turn and adjust the eye". It was also said to be a criterion for the slowly emerging intentions of Nazism. This is by and large a warped overstatement of a film that was impossible not to influence generations of artists, thinkers and, ultimately governing societies. Wiene's film was an inspiring footnote to the ever-increasing ascendancy of twenties Dada and Surrealism. F.W. Murnau's Nosferatu (1922) and Fritz Lang masterpieces Metropolis (1927) and M (1931) are just three exemplary paragons that owe their methods and poise to the work of Caligari. The archetypes forged - the villain, the hero, the deranged prisoner - became the blueprint for future directors. Despite its monochrome production, it's the film's use of colour and shading that stars. Every shot is a likeness to mania. Every intention is achieved. Caligari remains Germany's greatest gift to cinema.
