people let's not forget this as well...
This teaser was shown before Harry Potter 7 Part 2, look at the numbers HP7 is bringing in and the number of people going to watch HP7.
It's only going to build more hype from here on.
And in case anyone has any doubt, Tom Hardy is one fucking good actor. Also in case you didn't know, this movie will be the top grossing movie of 2012 and will be one of the best movies ever. Period.
