Is it true that 200 1 is an ape roaming in space?

Because Geoffrey ainsworth, the director of the film 200 1 A Space Odyssey, didn't want to use complicated special effects, all the special effects in the film were shot in front of the camera. Because the static background picture and the dynamic picture of back projection widely used at that time could not create the real effect that Kubrick wanted, this film pioneered the visual special effects technology of front projection. The African background in the film and a large number of spacecraft scenes in anthropological tool scenes are masterpieces of this special effects technology.
