Composers like John Williams and Hans Zimmer are known for their iconic scores that elevate the storytelling experience. These soundtracks can include orchestral pieces, songs, and sound effects that work together to create a cohesive audio experience. They play a crucial role in setting the mood, building tension, and guiding the audience's emotional responses throughout the film.
