"Thus in a sense movement has two aspects. On one hand, that which happens between objects or parts; on the other hand that, which expresses the duration or the whole. The result is that duration, by changing qualitatively, is divided up in objects, and objects, by gaining depth, by losing their contours, are united in duration. We can therefore say that movement relates the objects of a closed system to open duration, and duration to the objects of the system which it forces to open up.

Michael Snow and Vincent Grenier, two of the most important Canadian avant-garde film artistes, share an ironic and reflective sense of humour that involves the viewer in their works. Snow’s cinema stands out both for its brilliant formal research and its intellectual depth, which it uses to explore ideas about image, language and reality. Some of his most splendid works, such as Wavelength (1967), defined the sensibility of Vincent Grenier from the start of his filmic creation.
