10 Actors You Completely Forgot Were on 'Smallville'

If there's one thing Smallville excelled at, it was bringing new villains or introducing townsfolk in need of saving. Every great superhero needs someone to fight off or someone to save, and Clark Kent (Tom Welling) did plenty of both. From rescuing damsels in distress to going face-to-face with a meteor freak, nothing stopped Clark from his extracurricular duties. Throughout Smallville's run, there were several actors that made guest appearances on the show for either an episode or two. Many of them went on to lead their own hit TV shows, as was the case for Adam Brody and Paul Wesley.
