the Harry Potter movies - Harry vs. Voldemort and the death eaters
OR
Twilight - good vs bad vampires (Edward vs. James) -twilight could also be considered an example of character vs self - since it's about Edwards decision to either keep seeing Bella or to leave forever - in New Moon, he then decides that he is weaker than he believed, and leaves - through out the books/movies, Edward is against himself, and keeps making personal decisions about Bella and the others around him.
