You can get plenty of story out of a single villain, and even I'll admit the movies haven't made the best use of him. There's Superman, but Lex is somewhat marred by the comedic sidekicks, he's only a supporting villain in II, he's a bit closer to the comics version in IV but that's wasted on a bad movie, and his plan in Returns is just ridiculous.
If the villain is someone like Bizarro, Metallo, or Parasite, you can easily work him in as the one pulling the strings, or even the one who created them.
