“I won’t let go, Alvin. I won’t let go…” A very short teaser trailer for Fox’s next Chipmunks flick has just been posted on YouTube via VisoTrailers. The preview begins as though its an ad for James Cameron’s Titanic, only to have Alvin rather predictably shout that he’s “the king of the world” at the end of it. It may seem unoriginal, but on the plus side, at least no chipmunk dung is consumed by anyone in the trailer.  Alvin & the Chipmunks: Chip-Wrecked comes to theaters this Christmas.
