‘After Fistfight, Breer made three remarkably controlled animated films which turn to the forms and themes of his earliest work, but with more power and confidence than he ever had before. These three closely related films, 66 (1966), 69 (1968) and 70 (1970) place Breer for the first time as a major colourist amongst avant-garde film-makers. Each sets itself a clearly defined problem involving colour, speed, illusion and image shape, and even though they are unquestionably units of a series, they do not overlap or borrow from each other. Each fully satisfies its own postulated conditions of operation, seen together they clarify the subtle problems the film-maker has posed for cinema.’ – P.Adams Sitney.’ Visionary Film.’
