A profoundly meditative film, Circle explores many of Chambers’s central themes: the life cycle, the effect. To make it, he knocked a hole through the back wall of his home on Lombard Avenue in London and mounted a movie camera inside it. Each day for a year, he would turn it on for a few seconds, recording “blindly” whatever the lens saw. The result is a 24-minute chronicle of Chambers’s backyard and of time’s progress, bookended by a section showing the artist filming himself inside his house and found newsreel clips of London. The “circle” is complete and perfect in its form.
