The Dark Knight
Truthfully without Heath Ledger this movie would be rated significantly lower in my eyes. He is most certainly the star of the show in this film and blows everyone else out of proportion. I don't think there's even much more to say about his acting. To think that people thought he would let down the role of the Joker before the movie came out - looking back on others saying that now you can only just see how wrong they were. His role as the Joker is my undisputed favourite take on the character.
Overall the movie is very strong, the best one of the trilogy, and has some very beautiful shots. It looks amazing and is compelling to watch. Christian Bale is as good as ever.
