TCM’s annual “31 Days of Oscar” lead-up to the Academy Awards is underway again, and tonight the network is showcasing several of the winners in the Best Cinematography category. One of the most notable of these, 1976’s Bound for Glory, is an evocative biography of folk music icon Woody Guthrie, played by David Carradine. And I associate it, all these years later, as the first film in which I saw the Steadicam camera used, gliding in and above and around scenes like a bird – or, these days, like a drone. (It was, in fact, its cinematic debut.) Gorgeous photography. Poignant, still-pertinent story – and lyrics.
