MATT DAMON (JASON BOURNE) stars in this ALEXANDER PAYNE vehicle about a world where the capability of shrinking living beings is made a reality.
Being able to become five inches high, while irreversible, comes with many advantages, which fall into the categories of ecology and economy. Requiring less to sustain yourself scales what might be a meager savings for a full-size individual into a fortune for a miniaturized one, allowing for a retirement to leisure much earlier. Likewise, the less one uses, the less waste produced, so it's a win-win.
Payne does a wonderful job exploring the downsides of the technology as well -- particularly with political dissidents being shrunk against their will, and the challenges to illegal immigration if refugees can simply be shipped overseas by Federal Express.
