If there's one thing celebrity conspiracy theorists love, it's an undead famous person — and maybe the most iconic of all the potential vampire A-Listers is Nicholas Cage. The theory around his immortality is so popular that he's even been asked about it in interviews.

Similarly to Keanu Reeves and his historical dopplegangers, Nicholas has been accused of being a time traveller from the Civil War era. He's denied any truth in the matter (booooo), telling David Letterman, "There is a resemblance, but, how can I be polite about this," he asked. "It's a slowed down version of me..." But if a time traveling vampire was gonna give himself away that easily, then he wouldn't be very good at his job.
