"Red Dawn" is being remade, due out in November. Fun fact: The original was the first movie to receive the PG-13 rating, and was, in terms of deaths per minute, the most violent film ever made, at the time of its release.

Jupiter is a planet without a surface. The gas giant has a 700 mile gradient that begins with 40 miles of cloud cover, followed by hydrogen gas that gradually becomes denser, until it's liquid hydrogen. At some arbitrary boundary along there, one may consider the surface of the planet to have begun. But even that liquid hydrogen gradually becomes denser, until it becomes metallic hydrogen. It's only the very core of the planet that is rocky, a planet as we think of it. Jupiter might be interesting to scientists, but to the rest of us, it's barely a planet. Which makes sense, since Jupiter is basically a failed star.
