It's been three years since the 'The Dark Night' was released, and now, the wait to see the Batman again is almost over. A preview trailer for the final installment of Christopher Nolan's Batman trilogy, 'The Dark Night Rises', has been released. Although it doesn't show too much, it still gets you very excited for the movie. Well, at least it gets me very excited for the final movie in the trilogy. Can't wait! The movie is expected to be out July 20, 2012.
