Just riffing on your Matrix example, the now 'classic' example of using a temporal shift to aid story telling is the use of 45 or 90 degree shutter in "Saving Private Ryan" during combat scenes. Changing the shutter angle on a motion film camera is analogous to changing the shutter speed, in this case opting for a faster shutter during the action sequences. This reduces motion blur the same way shooting at a higher frame rate would, albeit keeping the 24p.
