I was fortunate enough to watch 2001 on a huge screen, at night, at the bottom of the Thompson dry-dock in Belfast ( in which the Titantic was constructed ). It was indeed an utterly different film when surrounded by enormous cold darkness.

It would have been interesting to have had the 'dialogue scenes' projected onto a smaller section of the screen and then expand out for the space scenes.

I think he held that reverse zoom on the landing bay too long, but nobody's perfect.

like the French, with their little enameled fly in the white of the urinal, in the movie theater you would not notice, watching the small Pan-Am aircraft rolling as it approached. Passengers would not feel the roll and be thanking the baby Elvis.
