Watch Room (Double Take) (1967) Official Trailer

A hand-held camera zooms in and out as it films the objects in a room. The same sequence is presented twice. "In Room, [Gidal] makes deliberate use of the complete repetition of a whole film [...]. The camera's movement is slow and in close up on the objects it passes, causing the viewer to mentally search ahead of its motion, particulary in the repeat". Malcolm Le Grice, Abstract Film and Beyond, 1977
