Which came first, Robert Thom's Esquire novella or his screenplay? Doesn't matter - the premise of "the youth vote" (as if it were monolithic, a consistent mistake during the Sixties) working to overthrow the establishment and creating a fully functional dystopia was a winner from the first word. Immaculately filmed despite the shoestring budget and remarkably well-acted by an amazing cast, the New York Times referred to it as the only film that year to "get it" in terms of the impact of youth culture. Academy award nomination for editing, largely from clipping what appears to be Monterey Pop footage and overlaying our presidential candidate, Max Frost. A delight then, a delight now. Nothing can change the shape of things to come.
