The rule of thumb in this film blogging world of ours is, what goes up must come down. In other words, any trailer that finds itself premiering on YouTube can only find itself taken down from YouTube. So, for now, let us offer you what appears to be the teaser for this winter's big-budget remake of The Day The Earth Stood Still, in which an alien visitor (Keanu Reeves) gives us Earth denizens a hefty heads-up that if we don't straighten up our act, he and his giant robot friend will do it for us ...

Now, I may or may not be entering spoiler territory with this following paragraph, so feel free to skip it (in that case, long story short: also stars Jennifer Connelly and due in theaters on December 12th) -- BUT, from what I can recall reading at one point, our main man's angle this time around is not concerns of nuclear warfare (that's SO 1951!), but rather more environmentally-fixated priorities. Who knew that between this, WALL-E, and The Happening that the big H'wood cared so much about the state of our planet.

On the other hand, pitched properly, green can only equal more green in their eyes.

(UPDATE:the Quicktime trailer appears to have gone up.)
