Frodo! How could we exclude Frodo, of all people from this list? Well, you probably already know, but his name isn't actually Frodo in real life, it's Elijah Wood, and Wood himself is every bit as geeky as his nether world counterpart. Wood's fascination with all things nerdy led him, of course, to his iconic role in the Rings trilogy, but he's also taken on interesting projects like voicing the series Tron: Uprising, numerous roles on Robot Chicken, and his creepy turn as a psychopathic killer in Frank Miller's Sin City. Aside from acting work though, Wood has other passions, including music, his record label Simian records which operates out of Brooklyn, New York.
