Best Visual Effects Winners are being saluted tonight on TCM’s “31 Days of Oscar,” and the prime-time showcase begins with what I consider the most far-reaching, astounding-for-its-time special effects and visual effects movie of all: Stanley Kubrick’s 1968 masterpiece, 2001: A Space Odyssey. It’s an astounding movie in every visual aspect, even before it gets to the part set in the future. Take, for example, that now-iconic black monolith. Not even the latest iPhones are that sleek.
