The boxer in Pulp Fiction was portrayed by Bruce Willis. Willis brought the character to life with his acting skills. The boxer's story in the movie is full of twists and turns. He has a past that catches up with him during the events of the film. His interactions with the other seedy characters in the movie create a really interesting and engaging narrative.
Uma Thurman played a significant role in 'Pulp Fiction'. She was Mia Wallace in the movie, with her performance being one of the most memorable aspects of the film. Her character was stylish, complex, and Uma Thurman brought her to life in a really captivating way.
I'm not sure if there's a character named Chopper in 'Pulp Fiction'. I might be misinterpreting your question, but I don't recall such a character in the movie.
Some of the notable songs in 'Pulp Fiction' include 'Misirlou' by Dick Dale. It has that really energetic and distinct surf rock sound which sets the tone right at the beginning of the movie.
The gimp in Pulp Fiction was played by Stephen Hibbert. His portrayal was quite interesting as the character is very much a part of the movie's darkly comical and somewhat surreal world. The gimp's appearance and actions are both disturbing and oddly humorous at the same time, and Hibbert did a great job of embodying this complex and unusual character within the framework of Quentin Tarantino's unique vision for the film.
