An hour ago I checked into the Acanthus hotel in Munich, and was thinking about taking a nap. Then this came in — a smart, well-honed 45-minute doc about 2001: A Space Odyssey with James Cameron, Keir Dullea, Douglas Trumbull, Dan Richter (the mime who played Moonwatcher), Elvis Mitchell, Camille Paglia, the late Arthur C. Clarke, etc. I found it here. Good stuff. I didn’t take the nap.
