The Oscar-winning 1970 concert documentary Woodstock celebrated its 40th anniversary a few years ago, but Warner Bros. is already re-revisiting. The new three-disc Blu-ray set, fittingly titled Woodstock 40th Anniversary Limited Edition Revisited, features the film’s four-hour director’s cut, two discs of extras, and a souvenir pack filled with reproductions of articles on the concert from Life magazine and The New York Times, a pair of reproduction concert tickets, and an embroidered iron-on patch with the classic dove-and-guitar logo.
