2. George Lucas The O.C.
Episode Appeared: The O. Sea (Season 2) No, really. That's the name of the episode. When most celebrities do cameos in certain things they usually just end up playing themselves inside of the show. George Lucas is no different. Who knows why Lucas decided to do a cameo, perhaps it was to advertise his latest film or perhaps he is just a fan of the show. Either way it was pretty cool to see George Lucas sit down and act. Seems like something that would usually be out of his comfort zone. His cameo involves him attempting to purchase a graphic novel from Seth and even if you aren't into The O.C. This cameo is still worth checking out.
