Ken Smith sez: You've got to admire Jam Handy; not many producers could make a film about car differentials that's as easy-to-understand and as visually interesting as this. The film's opening -- which uses motorcycle stunt riders as an analogy for "cornering" -- is kind of oblique, but then the narration and scale models kick in and the JHO is in its glory. Well done.
