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

I'd formed a research and development company under the banner of Paramount Pictures back in about 1975, and its mandate was to explore advanced forms of entertainment, not just movies.

2001' used a lot of what's called 'front projection.' You project an image onto this giant reflective screen, and the image bounces back and comes back to the lens and seems to be in the background behind the actors. The whole 'dawn of man' sequence in '2001' was projected eight-by-ten photographs of the African savannah.

The diversity of content is now offered from streaming and downloading, so young people are really not going to theaters because they don't see any particular benefit.
