What are some differences between Of Mice and Men in the novel and the motion picture, specifically for Curly?

I am writting an essay on the differences and similarities that are shown in "Of Mice and Men" in the novel version, and the motion picture version. Specifically I am working on a sim/dif essay that deals with Curley. Since I know the similarities, does anyone know any differences?
