The short documentary, 2001 A Space Odyssey: A Look Behind the Future is a fascinating artifact of film history. As the folks at Coudal Partners point out, it might be a little "cornball" at times, but it still serves to give context for thoughts around space exploration from technical experts and artists in the late 1960s.
