Nicolas Cage was put side by side with the Civil War era picture that's been sweeping the Internet in conjunction with a theory that he is in fact a vampire on "Late Show" (Weeknights, 11:35 p.m. EST on CBS). David Letterman presented the picture to him and while Cage acknowledged a resemblance, he didn't see a flattering one.

"How can I be polite about this," he said of the man in the picture. "It's a somewhat slowed down version of me."

Furthermore, he posited that the very existence of the picture would seem to denounce the vampire theory. After all, it's common knowledge that vampires' pictures can't be taken. "I don't drink blood and last time I looked in the mirror, I had a reflection, so I'm not going with the vampire theory," he concluded.

But there are two ways to interpret what's happening here. Perhaps the myths about vampire reflections and being able to take pictures of vampires are just that. Nicolas Cage could be a vampire following "rules" that humanity simply doesn't know yet. Or a far simpler explanation could be that he's just immortal. Meaning fans can look forward to more Nicolas Cage movies for the rest of their lives, as he'll outlive them all.
