If you have room on your DVR, record this for sure. Although the movie Woodstock: 3 Days of Peace and Music came out in 1970, a year after the massively attended Bethel, NY rock festival itself, this four-hour expanded Director’s Cut edition, shown tonight as part of TCM’s “31 Days of Oscar” salute to documentaries, wasn’t released until 1994. And in this case, more is better, and the strained, overwhelming size of the film just seems to mirror the subject itself. (“The New York State Thruway is closed, man!”) This director’s cut makes room for acts not seen in the original, including Creedence Clearwater Revival and Jefferson Airplane – and, of course, makes the most of the now-iconic performances by Jimi Hendrix and (pictured) Joe Cocker.
