This week sees the release of an extraordinary new teen movie, adapted from a book, involving social rebellion. I’m not talking about Divergent. And to be fair the film already opened last Friday but expands to Los Angeles this weekend followed by Austin, Atlanta, Boston and other major cities over the next two months. It’s titled Teenage, and it’s a documentary, and while it’s heavy on the archival footage, it’s very accessible, cleverly constructed and even quite entertaining. It’s produced by Jason Schwartzman, features character narration by Jena Malone and Ben Whishaw and features Alden Ehrenreich. And like any good teen movie should, it has a memorable soundtrack — albeit one totally in the form of an anachronistic electronic store by Deerhunter’s Bradford Cox. Although there were qualifiable entries here and there beforehand, the teen movie really was born in the 1950s, which is also around the time when we think of teen culture first beginning to emerge. The second part isn’t necessarily the case, though, even if it’s when the term “teenager” and the acknowledgement of adolescents’ pop culture finally caught on in the mainstream. Taking its basis from Jon Savage’s Teenage: The Prehistory of Youth Culture 1875-1945, the documentary takes us back much further in time to the last quarter of the 19th century. Think of it as the prequel or back story to every teen movie of the last 60 years. Except maybe Swing Kids, which deals with a social group also included in Teenage.
