Featuring a "director" of such omnipotent powers that Kubrick would seethe in jealousy, John Smith's THE GIRL CHEWING GUM(1976) is a classic and comedic* crowd-pleaser that I return to whenever I feel my senses are dulled. The joy of the film is not only in Smith's commandeering voice, but also in how he pinpoints our attention on this busy East London street, the eyes directed by the word, as Smith wittily upends any illusion of control. A cold glass of water in the desert of "mastery". You can find out more about John Smith on his website.
*Insert requisite line on how the avant-garde isn't known to have a sense of humor.
