Below is the third trailer, released on April 30, 2012. Following that is the first full trailer from December 2011.

"When Gotham is ashes", a seemingly victorious Bane says to a battered and bleeding Bruce Wayne, "you have my permission to die." 

That's one of the quotes from the first full length trailer for The Dark Knight Rises. The trailer shows a Gotham City in turmoil as the super-steroid enhanced villain, Bane, assembles his army of thugs. Take a look at what else Christopher Nolan and company have in store for us when The Dark Knight Rises opens on July 20.
