I'm both excited and sad to see these clips... It means the series are almost at an end!!! :-( I'm honestly much more sad to see Harry Potter end. I told my son tonight that I will definitely bawl like a baby when we go see it. Might as well take myself a box of tissue... As for Twilight, well, there will still be another film. I also feel like Harry Potter is a more epic creation. Its fan base, in my opinion, spans many more age groups and, I imagine, has many more male members :-).
Anyway... They both look great! I can't wait!!!
