American History X (1998) - IMDb user comments:

-Edward Norton is just unbelievable. He is the most talented actor I've ever laid eyes on. His performance in the movie is phenomenal. He delves so deep into his character that he can convince the whole audience easily of his neo-nazi role. The look on his face as he walks back from killing one man in the first seen is purely horrifying.

- Powerful portrayal of Neo-Nazi movement in America. Told in series of flashbacks. Flawless acting by Edward Norton. Does its best to make the point that no one is ever right aand no one is ever wrong. I have a friend who was a Nazi and a racist. But upon walking out of the theater after this movie he hung his head in shame. This is why the film industry began.

-Not many people know this, but Ed Norton's character, Derek, is based on an actual person -- a guy that went to my high school a few years before I did. He comes to speak every year at an anti-hate assembly. They show us clips of the movie (in my case, my English teacher let us watch the whole thing) and then he comes out and speaks. It's bizarre, to see him because he sounds exactly like Derek does after he gets out of prison. He's genuinely remorseful and what most people don't realize, is what a life-change that really is. Most Neo-Nazis and extreme racists are practically brainwashed in their points of view. It can take years, even lifetimes before they can be broken out of these harmful, violent mindsets. The movie seems slightly unrealistic in that way, that someone as intelligent and seemingly brainwashed as Norton's character, could make such a change from a short stint in prison. Well as I can firsthand tell you, it is possible, and the transformation did really happen. I can't remember the guy's name to save my life, but having that knowledge of the film and the people it's based on has made me appreciate this movie even more.
On a whole other side level, yet another amazing performance by Ed Norton. This man never ceases to shock and amaze me with his range and ability to adapt physically to any role thrown at him. I'm sure he wasn't the first choice for this role, I can think of plenty of other All-American looking actors that would seemingly fit better, even Furlong seems better fit to the Neo-Nazi role than the Norton we all know. However with a beefed-up physique and a well-written film to back him up, Norton shines in this role
