I first saw the trailer to this film around the time of the brilliant actor Heath Ledger's death. I was mesmerized by his character, and because of that, I vowed to see it opening night. Not only was The Dark Knight action-packed and creative, the plot and actors kept my attention throughout the entire 2 hours and 30 minutes of screen time, which no other movie had done before. Extra praise should be given to Heath, who in my opinion, determined the movie's success. He was so intriguing right from the very beginning. There were times when I was extremely frightened of him, since he was so unpredictable; other times, he made me laugh at him and with him; and at other times, I felt sorry for his character after being informed that his childhood contributed to his current, twisted state. After growing up watching Jack Nicholson's fantastic performance of the Joker, and then now watching Heath's performance, I believe that Heath brought more dimensions to the character than Jack. With Jack's performance, you mainly see a dark comical side; with Heath's preformance, you see a psychological, witty, dark, menacing, manipulative and violent side. Heath was so brilliant, that when he was not in a scene, I was literally praying for him to return! If you are not a Batman fan, then if for no other reason, go to see this movie for Heath's charismatic brilliance; the man should be given an Oscar for this performance, since this is his best one, in my opinion. It should also be said, that Morgan Freeman, Christian Bale, Michael Caine, Gary Oldman, and of course, Aaron Eckhart gave excellent performances as well. I will definitely be seeing this again since I have never felt so moved by an actor's performance like that in my life. Cheers Heath.
