The official trailer premiered online in December 5th, 2007. Also, the first uploaded on YouTube. There are plenty of websites out there telling the synopsis of the movie, or you could read the book yourself, so I won’t bother describing the story here ;) For the ones who wonder, YES, it is the White Witch inside the ice prison. Don't worry, this part IS in the book. (although SHE doesn't really appear, the idea is the same)
