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.
