Film composers are musicians who create original music for movies. Their work enhances the emotional impact of a film, helping to convey feelings and set the mood. Composers often collaborate with directors and producers to ensure the music aligns with the film's vision. These professionals use various instruments and technology to produce soundtracks that can range from orchestral scores to electronic music. Notable film composers include John Williams, known for his iconic scores in Star Wars and Harry Potter, and Hans Zimmer, famous for his work on The Lion King and Inception.
