« At the University of Kansas, I saw Joyce Wieland's Rat Life and Diet in North America for the eighth time, and it holds. [...] It may be the best (or richest) political movie around. It's all about rebels (enacted by real rats) and police (enacted by real cats). After a long suffering under the cats, the rats break out of the prison (in a full scale rebellion) and escape to Canada. There they take up organic gardening, with no DDT in the grass. It is a parable, a satire, an adventure movie, or you can call it pop art or any art you want—I find it one of the most original films made recently. »
