The Discovery centrifuge: the set turned, the actor walked.credit to be added

How do you film zero gravity a decade before the computer? Kubrick answered with engineering: a gigantic centrifuge that rotated as a whole while the actor walked in place, cameras bolted to the structure, the world turning around the scene.

For the dawn of man there was no location: front projection of African photographs onto a reflective screen, a technique pushed to its limit to place studio australopithecines under a real sky. The illusion is still perfect in 4K — and it is entirely optical.

The gate of light

The final voyage came from the slit-scan technique perfected by Douglas Trumbull: a slot of light photographed in very long exposures, frame by frame, night after night. The most imitated psychedelia in cinema is, at source, photographic craft.

Kubrick’s only competitive Oscar came precisely for the visual effects of 2001. Half a century later the benchmark is still there: no pixel ages as well as a well-built trick performed in front of the camera.
