We're not that far from being able to plant images, memories, and emotional states directly into the brain.

When I worked on 2001 - which was my first feature film - I was deeply and permanently affected by the notion that a movie could be like a first-person experience.

There's a consistency in my work that pops up independent of the limitations of the technology.

The technology of the time dictated the way things looked.

My particular aesthetic of light and color and design wouldn't change as a result of working with computer graphics rather than with slit scan or miniatures.

My first job on 2001 was to make all of the HAL readouts: the 16 screens that surround HAL's eyes.

It was the point where things became much more abstract and less literal than in the bulk of the film, which was hardcore rockets and space and planets - all a fairly straightforward evolution from what I had been doing before.

IBM was the original contractor for much of the computer interface design on the film.

I visited a scientist who had a helmet with magnetic fields controlled by computer sequences that could profoundly affect your mood and your perceptions.

I honestly believe that the next big leap in immersive technology will be very much like Brainstorm.

Clearly, if we'd had the kind of computer graphics capability then that we have now, the Star Gate sequence would be much more complex than flat planes of light and color.

But as far as the concept of HAL, who HAL was, his character - I had no role in creating him.

There were IBM logos designed for the film, and there were IBM design consultants working with Kubrick on the layout of the controls and computer screens.
