For now, Nolan and Batman will rest in 'Dark' glory

This morning i read an article on the USA today website about the the movie " the Dark Knight" I though that it was very interesting that the director is not sure if he wants to do a 3rd installment of the films trilogy because in the past films that done a 3rd film have not done as well as the previous 2 films. Also I thought that it was interesting that the director does not like to do bloopers, gag reels, or deleted scenes because he wants to show the integrity of the actors and the final product should be the only one with their faces on.
