Sé que es imposible (1925-1929)

Warsaw's Central Railway Station. 'Someone has fallen asleep, someone's waiting for somebody else. Maybe they'll come, maybe they won't. The film is about people looking for something.

A group of people are standing along the platform of a railway station in La Ciotat, waiting for a train. One is seen coming, at some distance, and eventually stops at the platform. Doors of the railway-cars open and attendants help passengers off and on. Popular legend has it that, when this film was shown, the first-night audience fled the café in terror, fearing being run over by the "approaching" train. This legend has since been identified as promotional embellishment, though there is evidence to suggest that people were astounded at the capabilities of the Lumières' cinématographe.

Extranjeros de sí mismos

Clouds 1969 by the British filmmaker Peter Gidal is a film comprised of ten minutes of looped footage of the sky, shot with a handheld camera using a zoom to achieve close-up images. Aside from the amorphous shapes of the clouds, the only forms to appear in the film are an aeroplane flying overhead and the side of a building, and these only as fleeting glimpses. The formless image of the sky and the repetition of the footage on a loop prevent any clear narrative development within the film. The minimal soundtrack consists of a sustained oscillating sine wave, consistently audible throughout the film without progression or climax. The work is shown as a projection and was not produced in an edition. The subject of the film can be said to be the material qualities of film itself: the grain, the light, the shadow and inconsistencies in the print.
