Good Homecoming Float Ideas?

Hello. I am in the 9th grade. Our Homecoming float theme this year is movies. It cannot be anything that would offend anyone, like religiously. The movies taken already are 300, Jaws, and Indiana Jones. I think we should do a movie with a good guy and a bad guy, and it has to be a movie that when shown to people, they will recognize it. Our mascot is the Aggie, and the other team's is either a bull dog or a wildcat.
