18. ‘THX 1138’ (1971)

As visually and sonically stunning as anything George Lucas would later do in a galaxy far far away, his future-fascistic nightmare is a pure product of the decade’s New Hollywood renaissance, exploring sex, drugs, mind-numbing television, governmental malfeasance, and both the necessity and futility of rebellion. Robert Duvall is quietly tremendous as the movie’s equivalent of 1984‘s Winston Smith. It’s not just a film, it’s a jumping-off point for an alternate universe in which George Lucas’s body of work veers closer to Sixties cerebral sci-fi than Thirties serials.

“What’s wrong?” I contributed a couple of items to Rolling Stone’s list of the 50 Best Sci-Fi Movies of the ’70s.
