It might be possible to use variable speed video playback software to make fast-paced action movies more comprehensible to older people whose brains don't process visual information as quickly any more. I'd like to see that experiment. Of course, at 75% speed, it would take exactly 3 hours to get through the visual assault of Speed Racer, and that might be more time than you'd be willing to commit to.
