1. Gollum’s Dual Personality Scene. This was the easiest choice for me. I thought the scene was great in the movie and was amazed at how well the animators had captured both the Smeagol (good Gollum) and the Gollum (evil) sides of the villain’s character. Once the DVD came out and I got to see how motion capture was used and understood the animators were simply transforming Andy Serkis’ performance, I realized why there had been a push to nominate Mr. Serkis for the Best Supporting Actor Academy Award. His performance is phenomenal.
Of course, the scene is not merely a marvelous feat of motion capture/animation, but one of the most moving scenes in the entire trilogy. Smeagol’s victory over his evil persona is a satisfying triumph for the viewer, and sets up his tragic fall when Frodo fails to protect him. Without this scene, Gollum remains a pathetic, spiteful creature. With it, he becomes the empathetic villain Lord of the Rings otherwise lacks, and thus provides a far greater depth to the story.
Most interestingly, this scene–as it is written–exists only in the movie, not in the book. Tolkien certainly hinted at Gollum’s schizophrenia, but it took the writers, the animators, and especially Andy Serkis to bring it to life. This brief video shows a side-by-side clip.
