Melancholia

This movie looks pretty interesting.  The idea of a planet on a collision-course with Earth is pretty scary.  For what I'm assuming is done to keep the story succinct, the planet apparently has been hiding behind the sun (for how long?) and will soon pass by (collide) with Earth.  Not the most plausible premise, but there is some basis for the collision with rogue planets.  A rogue planet is one that wanders the galaxy (perhaps the universe too?) freely.  I'm sure the chances are not high of this actually happening, but it's interesting to think about a sort of slow approach to the end of the world that we can see coming but are powerless to stop.
