I mentioned this a few days ago, but here it is again, with a few more details, courtesy of the American Cinematheque press release:
The American Cinematheque at the Egyptian Theatre presents a special limited weekend-long engagement of maestro Stanley Kubrick's mind-expanding 2001: A SPACE ODYSSEY (1968, Warner Bros. Classics, 139 min.) in glorious 70mm. If you think you've seen "2001," think again - until a few years ago, the film was availableonly in a 35 mm version that reduced Kubrick's legendary visuals (and the spectacular 6-track stereo sound) to a pale shadow of their true glory. Before his death, Kubrick oversaw a painstaking, frame-by-frame restoration of the film in 70mm, resulting in a version that looks and sounds as good as (if not better than) the original 1968 release!
Master filmmaker Stanley Kubrick'ssenses-melting excursion into the far reaches of the universe and the unfathomable mysteries of time and space is based on a 1948 short story "The Sentinel" by Arthur C. Clarke, "2001" was reconceived by Kubrick himself, working with author Clarke to create the ultimate Journey Into the Unknown.
